The correct answer is option 4, Mohammad-Bin-Tughlaq. Mohd-Bin-Tughlaq was a Sultan of Delhi from the Tughlaq dynasty. He is known as the "Prince of Moneyers" because of his attempts at currency reform. During his rule, he introduced brass and copper coins to replace silver ones, in an effort to stabilize the economy. However, this move resulted in inflation and caused economic hardships for the people. He also experimented with the idea of a token currency, where the actual value of the coins would be different from their face value. These policies were largely unsuccessful and led to economic turmoil in his kingdom. As a result, Mohammad-Bin-Tughlaq is often criticized for the mismanagement of the economy during his reign.
