Explanation:

In the revenue administration of Delhi Sultanate, the in-charge of revenue collection was known as ‘Amil’. Hence statement 1 is correct.

lqta is an Arabic word and the institution had been in force in the early lslamic world as a form of reward for services to the state. It was used in the Caliphate administration as a way of financing operations and paying civil and military officers. It was not an ancient indigenous institution. The initial Turkish conquests in India in the early 13th century displaced many local chiefs. In order to consolidate, the Turkish rulers made revenue assignments (iqta), in lieu of cash, to their nobles. So, Iqtas were provinces or spheres of influence which were put under the charge of officers called 'Iqtadars' (governors). Hence statement 2 is not correct.

In Akbar's administration, the military department was headed by Mir Bakshi which looked after all matters pertaining to the military administration. He was also considered as the head of nobility. Hence statement 3 is not correct.
