The correct answer is: Diwan-e-Amir-Kohi.
Diwan-e-Amir-Kohi was the head of the market control system in Alauddin Khilji’s empire. He was responsible for ensuring that the prices of goods were kept stable and that there was no hoarding or profiteering. He also oversaw the collection of taxes on goods sold in the markets.
Shahan-e-Sahi was the title given to Alauddin Khilji himself. Shahan-e-Rajukas was the title given to the chief minister. Shahan-e-Mandi was the title given to the head of the market.
The market control system was an important part of Alauddin Khilji’s economic reforms. It helped to ensure that the prices of goods were affordable for the people and that there was no shortage of essential goods. The system also helped to generate revenue for the state.
