Which of the following is/are correct about Muhammad-Bin-Tughlaq's agrarian reforms? 1. A separate department, Diwan-i-amir-i-kohi was set during his reign. 2. Taccavi or agricultural loans were introduced under his reign, which was discontinued by Firuz Shah Tughlaq. Select the correct answer using the code given below:

• Muhammad-Bin-Tughlaq launched a scheme to extend and improve cultivation in the doab. He set up a separate department, called Diwan-i-amir-i-kohi.

• The area was divided into development blocs, headed by an official, whose job was to extend cultivation by giving loans (taccavi) to the cultivators and to induce them to cultivate superior crops—wheat in place of barley, sugarcane in place of wheat, grapes and dates in place of sugarcane, etc.

• The scheme failed largely, because the men chosen for the purpose proved to be inexperienced and dishonest, and misappropriated the money for their own use. The large sums of money advanced for the project could not be recovered.

• Fortunately for all concerned, Muhammad Tughlaq had died in the meantime and Firuz wrote off the loans. But the policy advocated by Muhammad Tughlaq for extending and improving cultivation was not lost. It was taken up by Firuz and even more vigorously later on by Akbar.
