Historians used inscriptions, coins, and literary evidence to reconstruct dynastic histories, including that of the Mauryas. Chandragupta Maurya indeed founded the Mauryan Empire around 321 BCE. However, this fact does not explain why inscriptions are useful for reconstructing lineages. Therefore, both statements are true, but the Reason is not the correct explanation.

Asokan inscriptions reveal a vast empire and adaptation to local linguistic traditions. However, historians caution against assuming that uniform messages meant uniform administration. Different regions had varying geographical, economic, and political conditions. Therefore, Option C is the incorrect conclusion because it overstates the degree of administrative uniformity.

Historians suggest that displaying an inscription expressing remorse over a recent conquest in the conquered region may have been politically insensitive. The absence does not deny the war's occurrence. Options A, B, and C lack supporting evidence and are not accepted historical explanations.

Most Asokan inscriptions were written in Prakrit using Brahmi script. In Afghanistan, inscriptions appeared in Greek and Aramaic. Kharosthi was used in the northwestern parts of the empire. These regional adaptations helped communicate Dhamma effectively to diverse populations, making Option A correct.

Taxila and Ujjayini occupied strategic positions on major trade routes. These routes encouraged commerce, facilitated movement of officials, and strengthened administrative control. Their importance came from connectivity rather than proximity to gold mines, Mediterranean routes, or exclusive agricultural advantages.

The sequence begins with the emergence of Mahajanapadas. Early rulers often depended on militias recruited from peasants. Over time, stronger states developed standing armies and bureaucracies. The Mauryan Empire later created a highly structured administrative and military organization, including committees and subcommittees. Hence, Option C is correct.

According to Megasthenes, the second military subcommittee handled transport, supplies, and support services. This included arranging bullock carts, procuring food, and recruiting servants and artisans to assist soldiers. Such duties reflect the complexity of Mauryan military administration. The other options do not match Megasthenes' description.

Elephants formed an important part of ancient Indian warfare and significantly strengthened Magadha's military capabilities. Forests in and around Magadha provided a ready supply of elephants, making them available for military use. Thus, both statements are correct, and the Reason directly explains why elephants became a strategic advantage.

Land journeys in the Mauryan period often took weeks or months. The second military subcommittee organized transport, food supplies, carts, support personnel, and security. These responsibilities were essential for communication and movement across the empire. The committee did not primarily build roads, translate inscriptions, or map stars.

River routes were vital for trade, administration, and military movement because they were cheaper and more efficient than many land routes. Pataliputra benefited from its riverine location, and officials supervised waterways. The claim that rivers were reserved only for the royal family is historically incorrect, making Option D the wrong statement.

After the Kalinga War, Asoka increasingly emphasized Dhamma as a means of governing a vast and diverse empire. Dhamma mahamattas were appointed to spread ethical principles and promote welfare. This reflects a strategy of ideological integration rather than reliance solely on conquest. The other options misrepresent their functions.

Megasthenes described officials measuring land in a manner comparable to Egyptian assessment methods. Sluice inspection ensured equitable water distribution. Tax collection generated state revenue. Superintendents monitored occupations such as woodcutting and mining. These functions match Option C accurately.

Modern historians argue that Mauryan administration was not equally strong in all regions. The empire existed for roughly 150 years and governed diverse territories with varying degrees of control. Therefore, the Reason correctly explains why historians today view Mauryan authority as less uniformly pervasive than earlier interpretations suggested.

The Mauryan Empire covered regions with vastly different geography, economies, and societies. While inscriptions carried similar messages, actual administration likely varied according to local circumstances. Thus, historians caution against assuming uniform governance merely because inscriptions appear similar across distant regions.

The passage explicitly states that chiefs received gifts from subordinates and redistributed them among supporters. This differs from kings, who usually relied on regular taxation. Therefore, Option B correctly captures the distinction. The other options introduce features not mentioned in the passage.

The passage states that a chief derived support from kinfolk and that the position may or may not be hereditary. This directly supports Option C. The passage does not mention democratic elections, caste restrictions, or mandatory standing armies as defining characteristics.

The Kushanas projected divine kingship through multiple media. Their coins depicted rulers alongside deities, while colossal statues installed in shrines visually reinforced royal prestige and sacred status. These representations strengthened political legitimacy. Relic caskets, iron pillars, and terracotta toys were not the primary symbols of Kushana divine kingship.

The title Devaputra ("Son of God") helped Kushana rulers project divine status and justify authority over a vast and diverse empire. Such ideological claims enhanced prestige and legitimacy. Options B and C contradict the purpose of divine kingship, while D incorrectly interprets the influence of similar foreign traditions.

Chiefs relied on gifts and kinfolk support (c). Kings maintained authority through taxation and armies (d). Samantas sustained themselves through local resources while supporting overlords (b). Devaputra represented rulers claiming divine legitimacy (a). Therefore, the correct matching is 1-c, 2-d, 3-b, 4-a.

Historians extract factual information from prashastis while carefully accounting for exaggeration and royal praise. The Prayaga Prashasti was indeed composed in Sanskrit by Harishena, Samudragupta's court poet. However, the identity of the author does not explain why historians use the inscription as a historical source. Thus, both statements are true but unrelated.
