Which of the following is NOT correctly matched?

1. A

   Dam Copper coin

   Dam was a copper coin of the Delhi Sultanate/Mughal system (40 dams = 1 rupee in Akbar’s later account). The pair is treated as correct.

2. B

   Desai Revenue Collector

   Desai was a revenue collector/official in parts of western India (Maratha/Deccan usage). Treated as correctly matched.

3. C

   Diwan Revenue Chief of a province

   Diwan (diwan-i-wizarat / provincial diwan) headed revenue in a Mughal province. Correct pair.

4. D

   Jarib – A type of tax

   Jarib is a measuring chain/rod and the system of land measurement (zabt/jarib), not ‘a type of tax’. That mismatch makes (d) the official key.
