Diwan-i-Arz was related to which work?

Correct answer: Military department

Direct answer: Option D, the military department. In the Delhi Sultanate, Diwan-i-Arz was the department responsible for military administration. It dealt with matters such as soldiers, recruitment, organisation, inspection and military records. The word arz is a useful association with the army department in this context. Option D is correct. Option A, revenue farming, concerns the collection or assignment of revenue and is not the main function of Diwan-i-Arz. Option B, painting, was an artistic activity, not a Sultanate administrative department under this name. Option C, temple building, was not the responsibility of this office; the Sultanate’s military department had a different purpose. The question tests matching an office with its function, so focus on administration rather than the literal appearance of the words. Remember the pair: Diwan-i-Arz—army; Diwan-i-Wizarat—finance and revenue administration.
