Which medieval Sultan of Delhi is credited with establishing the 'Diwan-i-Riyasat', a separate department to strictly control market prices and ensure the supply of essential commodities?

💡 Solution & Explanation

Alauddin Khilji established the Diwan-i-Riyasat as a separate department to strictly control market prices, regulate merchants, and maintain the steady supply of essential commodities during his reign. Other options like Firoz Shah Tughlaq focused on public works and charitable endowments through departments like Diwan-i-Khairat rather than strict price controls.
