Option b is the correct answer. The Rajukas were officials in the Mauryan administration. The term "Rajuka" is derived from "rajju," possibly referring to land measurement using ropes. Rajukas were vital Mauryan administrators overseeing districts. They managed taxation, records, and governance, ensuring efficient local administration. Their role contributed to organized governance and revenue collection. Important Tips Administrative structure of the Mauryan Empire: The administrative structure of the Mauryan Empire featured a hierarchical system that facilitated efficient governance. Provinces and Divisions: Provinces were divided into divisions, each overseen by a Pradeshika. These officials lacked advisory councils. Districts and Rajukas: Divisions were further divided into districts, led by Rajukas. Rajukas managed local governance, taxation, and records. They were assisted by Yuktas (clerks) for accounting and secretarial tasks. Sub-district Administration: Districts were divided into smaller groups of 5 or 10 villages. Each group was supervised by a Sthanika responsible for tax collection. Gopas supported Sthanikas by maintaining accurate records and accounts. Village Governance: The village was the smallest administrative unit, led by a Gramini/Gramika. Village decisions were made in consultation with Grama-vriddhas, or village elders. Overall Structure: The Mauryan administrative structure resembled a pyramid, with the king at the apex and Gramini at the base. Variations in administrative control existed across different regions, with the central province, Magadha, under stricter royal supervision.
