Who among the following translated 300 volumes of Sanskrit books collected by Firoz Tughlaq during the campaign of Nagarkot?

1. A

   Azizuddin Khan

   Azizuddin Khan translated the 300 Sanskrit books collected by Firoz Shah Tughlaq during the Nagarkot campaign into Persian, entitling the work Dalail-i-Firuzshahi. This extensive translation project reflects the Sultan's interest in classical Indian philosophy and sciences, making this option the correct key.

2. B

   Talib Amuli

   Talib Amuli was a prominent Persian poet who served at the court of Jahangir and held the title of Malik-ush-Shu'ara, living long after the Tughlaq dynasty. He had no involvement in translating Sanskrit texts during the reign of Firoz Shah Tughlaq.

3. C

   Mulla Abdul Baqi

   Mulla Abdul Baqi is known for his historical and literary contributions during the later Mughal period, particularly under Jahangir. He did not translate the Sanskrit manuscripts collected by Firoz Shah Tughlaq after the Nagarkot expedition.

4. D

   Mirza Muhammad Ali

   Mirza Muhammad Ali was a court figure and litterateur from a much later period in medieval Indian history. He is unrelated to the early translation bureau established under the Tughlaqs for Sanskrit texts.

Summary. Official key is (a) Azizuddin Khan. Firoz Shah Tughlaq commissioned the translation of Sanskrit texts acquired during his Nagarkot campaign into Persian. Azizuddin Khan undertook this monumental task under the title Dalail-i-Firuzshahi. The other options refer to literary figures from the Mughal era who lived centuries later. Therefore, option (a) is the only historically accurate choice.
