The Assertion is true because even a very large capitalist company is treated as an individual economic agent in microeconomics. The size of the firm does not change the level of analysis. The Reason is also true because a firm primarily seeks to maximize the interests of its owners or shareholders rather than pursuing the welfare of the entire economy. This individual objective is why firms are analysed under microeconomics. Since the Reason correctly explains the Assertion, Option C is the correct answer.

1 → c : Microeconomics studies the behaviour of individual consumers, firms and markets through demand and supply. 2 → d : Aggregate output reflects the tendency of production across the economy to move together. 3 → a : A representative good corresponds to the average production level of all goods and services. 4 → b : Macroeconomics studies the health and performance of the economy as a whole. Therefore, Option D is the correct answer.

The consumer first identifies personal tastes and preferences (1). Next, the consumer considers the available income or budget constraint (2). Based on preferences and income, the optimum combination of goods is selected (3). As a result, the consumer achieves the highest possible level of satisfaction or utility (4). Therefore, the correct sequence is 1 → 2 → 3 → 4.

Producer's profit is the income that remains after paying all factor payments from total revenue. These payments include rent for land, wages for labour and interest for capital. Therefore, P = R − (L + W + I) This equation correctly represents the entrepreneur's profit. Hence, Option B is the correct answer.

(1) is correct because General Equilibrium is a concept developed within microeconomics. (2) is incorrect because general equilibrium does not ensure full aggregate employment under all circumstances. (3) is correct because it studies the simultaneous equilibrium of demand and supply in individual markets. (4) is correct because the analysis primarily concerns individual interconnected markets rather than aggregate macroeconomic variables. Therefore, Statements (1), (3) and (4) are correct, making Option A the correct answer.

Macroeconomics examines the common movement of aggregate variables such as prices, employment and output. When these variables move together in the same general direction across the economy, they indicate macroeconomic trends such as inflation, recession or depression. Therefore, Option A is the correct answer.

In a capitalist economy, entrepreneurs organize production and bear risks with the objective of earning profits. After paying wages, rent and interest, the remaining income is profit. A significant portion of this profit is often reinvested in future production and investment expenditure. Therefore, Option B is the correct answer.

The primary objective of producers in a capitalist economy is to maximize profit. Since profit equals total revenue minus total cost, reducing production costs directly increases profit margins. Therefore, producers strive to keep costs as low as possible, making Option C the correct answer.

In microeconomics, welfare levels refer to the satisfaction or utility that consumers derive from consuming goods and services. Consumers make choices that maximize this satisfaction subject to their income constraints. Therefore, Option A is the correct answer.

1 → c : Wages are paid to labourers for their labour services. 2 → d : Profit is earned by entrepreneurs for organizing production and bearing risk. 3 → a : Rent is the income earned by landowners for providing land. 4 → b : Interest is earned by capital lenders for supplying capital. Therefore, Option B is the correct answer.

Inflation refers to a sustained rise in the general price level across the economy. Since traditional microeconomics concentrates on individual consumers, firms and markets, economy-wide phenomena such as inflation are usually treated as given rather than analysed in detail. Therefore, Option C is the correct answer.

The classical school believed that markets would automatically adjust to ensure full employment. According to this view, anyone willing to work at the prevailing wage rate would eventually find employment. The Great Depression demonstrated that this assumption was unrealistic, leading to the development of modern macroeconomics by Keynes. Therefore, Option D is the correct answer.

The Assertion is true because macroeconomics often uses a single representative or imaginary commodity to simplify the analysis of aggregate output and prices. The Reason is false because this simplification is justified by the tendency of prices, output and employment of different commodities to move in the same general direction, not in completely opposite directions. Therefore, Option B is the correct answer.

Institutions such as the Reserve Bank of India (RBI) and the Securities and Exchange Board of India (SEBI) regulate important sectors of the economy to promote financial stability, efficient resource allocation and public welfare. Their objective is to serve the interests of the economy as a whole rather than any individual or private group. Therefore, Option C is the correct answer.

The sequence begins with Adam Smith's classical idea that individuals pursuing self-interest promote economic welfare (1). Later, economists observed that some markets either failed or did not exist (2). These shortcomings highlighted the need for government intervention (3). Consequently, macroeconomic policy tools such as fiscal and monetary policies were developed to address economy-wide problems (4). Therefore, the correct sequence is 1 → 2 → 3 → 4.

During the Great Depression (1929–1933), factories remained idle and unemployment rose dramatically because aggregate demand was insufficient. This represented a situation of macroeconomic disequilibrium where the economy failed to achieve full employment and stable production. Therefore, Option A is the correct answer.

During the Great Depression, the United States experienced one of the most severe employment crises in history. The unemployment rate increased dramatically from about 3% before the crisis to nearly 25%, highlighting the failure of the classical belief in automatic full employment. This experience played a major role in the development of modern macroeconomics. Therefore, Option C is the correct answer.

1 → c : Primary health aims at improving medical welfare and public health. 2 → d : Administration is responsible for enforcing laws and maintaining governance. 3 → b : Employment focuses on creating job opportunities and reducing unemployment. 4 → a : Defence ensures the security and protection of the nation. Therefore, Option D is the correct answer.

The passage clearly states that institutions such as the State, RBI and SEBI pursue public goals established by law or the Constitution rather than maximizing private profit or individual welfare. This distinguishes them from private firms, whose primary objective is profit maximization. Therefore, Option A is the correct answer.

The Reserve Bank of India (RBI) is the central bank of India. It formulates and implements monetary policy, regulates the banking system and manages the money supply to maintain price stability and support economic growth. Therefore, Option B is the correct answer.
