Which of the following is NOT correctly matched ?

The correct answer is D. Jarib is the measuring chain (a rod or chain of fixed length) used to survey and measure land in Akbar's revenue settlement. It was an instrument of measurement, not a tax. The tax assessed on that measured land was the zabti, so the match 'Jarib; a type of tax' is wrong.

The other three matches hold up. Dam was a copper coin, one-fortieth of a rupee in Akbar's monetary system. Desai was a hereditary local revenue officer, especially in the Deccan, who looked after revenue records and collection over a group of parganas. Diwan was the head of the revenue department, at the centre as Diwan-i-Kul and at the provincial level as the revenue chief of a subah.

The concept here is Mughal revenue administration under Akbar and Todar Mal, the zabti system based on measurement and assessment. For Mains, this links to the agrarian structure and the evolution of land revenue policy from the Mughals to the British settlements.

Trap: aspirants see 'jarib' and 'zabti' as interchangeable because both belong to the same system. Remember that the measuring tool and the tax based on it are different things.
