Correct Answer: Tax assessment

Solution : The correct option is Tax assessment.

The Department of Land Revenue was under the command of an official called Samaharta in the Mauryan administration system. The Mauryan Empire relied heavily on agriculture as a source of money; hence, this job was essential to the management and collection of this revenue. The Samaharta played a key role in overseeing the assessment and collection of land taxes and ensuring that the revenue reached the imperial treasury efficiently.
