During the regime of which Sultan was the Khalisa land developed on a large scale?

Correct answer: (b) Alauddin Khilji

Explanation

The main objective of Alauddin’s revenue and land-tax system was to establish a powerful and autocratic state. He confiscated land from those persons who had received it as milk-idrar, inam, and waqf (land received as a religious/ charitable endowment), etc. As a result, Khalisa land was developed on a large scale.
