Harappan cities were located in an alluvial plain where clay was readily available for pottery and brick-making. However, resources such as timber, stone, and metals had to be obtained from distant regions. Therefore, Statement 2 and Statement 3 are correct. Statement 1 is incorrect because many important raw materials were procured from outside the cities. Hence, Option C is correct.

The Harappans adopted different strategies for obtaining valuable materials. Shortughai was established near lapis lazuli sources in Afghanistan. Copper was procured from the Khetri region of Rajasthan. Lothal was situated near carnelian sources. Gold was obtained from South India. Thus, the correct matching is 1-c, 2-d, 3-b, and 4-a, making Option A correct.

The Assertion is true because materials such as stone, timber, and metals were sourced from outside the alluvial plain. The Reason is also true because terracotta bullock-cart models indicate the use of land transport. However, the Reason only suggests one transport method and does not directly explain why materials had to be procured externally. Therefore Option B is correct.

The Indus River and its tributaries formed an important transportation network within the Harappan civilization. Goods could be moved efficiently through riverine routes alongside coastal and land-based transport systems. The Ganga, Narmada, and Brahmaputra were not the principal river systems associated with Harappan trade. Hence Option D is correct.

Evidence from Oman includes Harappan jars coated with black clay and copper artifacts showing nickel traces similar to Harappan objects. These findings indicate trade contacts between the two regions. However, there is no archaeological evidence that Omani copper was primarily exchanged directly for Harappan gold. Therefore, Option A is the incorrect statement and the correct answer.

Mesopotamian records describe Meluhha as a region associated with maritime activity. Archaeological discoveries of seals depicting ships and boats provide direct evidence supporting these textual references. Option B therefore best corroborates the claim. Bullock carts and ploughs relate to land transport and agriculture, while the Great Bath has no connection with seafaring.

The Ganeshwar-Jodhpura culture possessed a large number of copper objects and was located near the Khetri copper belt. Archaeologists therefore suggest that it supplied copper to Harappan settlements. There is no evidence of warfare-based conquest, Mesopotamian colonization, or development of an alphabetical script. Hence Option C is correct.

Lapis lazuli, a distinctive blue stone, was obtained from Afghanistan and was highly prized in Harappan craft production. Carnelian is reddish-orange, jasper has different colours, and steatite is a soft stone used for seals and beads. Therefore, Option D correctly identifies the valuable blue stone sought by Harappan artisans.

Harappan seals combined script with animal motifs. Scholars suggest that the motifs helped communicate meaning to people who could not read the script. They likely served as recognizable symbols or identifiers. There is no evidence that they indicated exact weights, represented only deities, or described dietary preferences. Therefore, Option B is correct.

Harappan seals were used to secure bags and containers. If the clay sealing remained intact upon arrival, it indicated that the package had not been opened or tampered with during transit. This was an important mechanism for maintaining trust in trade. Therefore, Option C is correct. The remaining options have no direct connection with seal function.

Archaeologists infer writing direction from seal inscriptions. The engraver likely began from the right side, engraved initial signs with wider spacing, then realized insufficient space remained, forcing later signs to be cramped on the left. This pattern supports right-to-left writing. Therefore, the sequence 3 → 1 → 2 → 4 is correct, making Option A the answer.

Archaeological evidence shows Harappan writing on a variety of objects including rims of jars, copper tools, bone rods, and even large signboards. This demonstrates a broader use of writing beyond seals. Options A, B, and C incorrectly restrict writing to specific locations or objects unsupported by evidence. Therefore, Option D is correct.

Harappan weights followed a standardized system and were used to regulate trade. Smaller denominations were ideal for measuring lightweight, high-value goods such as beads, precious stones, and jewellery. Large quantities of grain, carts, or heavy metal ingots would require much larger measures. Therefore, Option C is the correct answer.

The Harappan weight system used a binary sequence in its lower denominations. Beginning with 1, 2, and 4, each subsequent weight doubles the previous value. Therefore the next two weights are 8 and 16. Options B, C, and D break the doubling pattern and do not fit the standard sequence. Hence Option A is correct.

The passage highlights the remarkable uniformity of pottery, seals, weights, and bricks across the Harappan region. Such consistency suggests that complex decisions were made and effectively implemented over a large area. This points toward some coordinating authority or administrative mechanism. Options A, C, and D are unsupported interpretations. Therefore Option B is correct.

The passage highlights that Harappan bricks maintained the same ratio across a vast geographical area extending from Jammu to Gujarat. This standardization existed even though bricks were produced in different centres. Such consistency suggests effective implementation of common norms. Therefore Option D is correct, while the other options are unsupported by archaeological evidence.

The famous Mohenjodaro stone figure was called the "priest-king" because early archaeologists compared it with Mesopotamian examples where rulers sometimes held religious authority. No deciphered Harappan inscription identifies the figure. There is also no evidence of a crown or throne. Therefore, Option D correctly explains the origin of the label.

Supporters of the single-state theory point to region-wide similarities in town planning, weights, seals, and especially standardized brick ratios. Such uniformity suggests some common administrative authority or coordinated system. The Great Bath alone cannot prove political unity, while the other options are unsupported. Therefore Option B provides the strongest argument.

Archaeologists have suggested environmental factors such as climatic change, deforestation, excessive flooding, and shifting river courses as possible causes behind the decline of some Harappan settlements. However, these explanations do not account for the collapse of the entire civilization. The remaining options lack archaeological support. Therefore Option C is correct.

The Late Harappan phase witnessed major transformations in material culture. Writing disappeared, long-distance trade declined, and many specialized crafts lost importance. Urban centres gave way to more localized cultural patterns. There is no evidence for coinage, larger citadels, or precious-metal weight systems. Therefore, Option A correctly describes the Late Harappan phase.
