Q. Consider the following administrative reforms:

1. Introduction of the Dag (branding of horses) system.
2. Creation of a separate department for slaves (Diwan-i-Bandagan).
3. Establishment of a public hospital system (Dar-ul-Shifa).
4. Foundation of the city of Hissar-Firoza.

How many of the above are specifically associated with the reign of Firoz Shah Tughlaq?
Answer: Only Three
Notes: Statements 2, 3, and 4 are associated with Firoz Shah Tughlaq. He established the Diwan-i-Bandagan for managing slaves, founded public hospitals called Dar-ul-Shifa, and built cities such as Hissar-Firoza. The Dag system (statement 1) was introduced earlier by Alauddin Khalji for military reforms.
