The official ‘Agronomai’ during Mauryan age was related with which of the following field?

The answer is D (Revenue management). The term comes from Megasthenes' account of the Mauryan state, where the agronomoi were superintendents of land. Their work was to measure cultivated land, supervise irrigation channels and canals, and regulate the distribution of water. Because land measurement and the assessment of produce formed the base of the agrarian revenue system, they are read as revenue and land administration officials.

Why the others are wrong:

• A (Weight and measurement): This was the work of officials like the pautavadhyaksha in the Arthashastra, not the agronomoi, who dealt with land.
• B (Administrative management): Too broad. General administration was spread across the samaharta, sannidhata and other offices, and the question asks for a specific field.
• C (Construction of roads): Strabo does mention distance pillars on highways, so this is the trap. But road building was not the core function the question is testing, and it is not the field the standard key points to.

Core concept: Mauryan agrarian administration, including land survey, irrigation and revenue. This links to Mains questions on the state's role in agriculture and the evolution of land revenue systems from the Mauryas to the Delhi Sultanate.

Trap: Picking C because of the road milestones, or picking B because the option sounds general. Anchor the term to land and revenue.
