The correct answer is option-4: A is false but R is true.
Explanation:
The assertion claims that Firuz Shah Tughlaq did not levy jizya tax, while the reason states that his influential minister Khan-i Jahan Maqbul was a converted Hindu. The reason is true because historical records confirm that Khan-i Jahan Maqbul, who held a prominent position in Firuz Shah Tughlaq`s court, was a converted Hindu.
However, the assertion is false. Firuz Shah Tughlaq did levy jizya tax during his reign as the Sultan of Delhi from 1351 to 1388. The jizya tax was a tax imposed on non-Muslims living in Islamic territories. This tax was one of the sources of revenue for the Sultanate and was implemented by Firuz Shah Tughlaq as part of his administration`s economic policies.
Therefore, while the reason is true, it does not serve as a correct explanation for the assertion.
