D. Mahmud Tughlaq

Answer: Option B

Solution(By Examveda Team)

Tughlaq found it difficult to maintain the supply of gold (dinars) and silver (adlis) coins on a large scale. So, he introduced a token currency system and minted vast quantities of new copper and brass coins (tankas) that could be exchanged for fixed amounts of gold and silver.
