01 What did Iltutmish's introduction of the tanka coin strengthen?
Answer and explanation
Correct answer: D. Economic and administrative system of the Sultanate
Explanation: Correct answer: D. Iltutmish, an important ruler of the Delhi Sultanate, established the silver tanka as a recognised coin. A standard coin helped make payments, revenue collection and official transactions more regular. It also supported administrative coordination because the state could use a more consistent monetary system across its territories. Thus the tanka is connected with strengthening the economic and administrative structure of the Sultanate. A is related to Chola architecture, not Sultanate currency. B belongs to Mughal cultural history. C belongs to the Gupta period and concerns literature. Memory cue: Iltutmish and tanka—think standard silver currency supporting Sultanate administration.
