Ans: (d) Sikandar Lodi

Explanation: Sikandar Lodi was the Sultan of Delhi between 1489 to 1517 AD. He was a laborious, generous and just ruler. Owing to a transient shortage of maize, he abolished the zakat on grain and it was not renewed by any subsequent Sultan. The prices of all necessary articles remained low during his period.
