When did Sher Shah Suri become the king of Delhi?
D
Correct answer
Explanation
Sher Shah Suri defeated the Mughal emperor Humayun in the Battle of Kannauj (1540) and established the Sur Empire, becoming the king of Delhi. He ruled until 1545 and introduced significant administrative reforms. The other dates (1522, 1530, 1532) are incorrect - Sher Shah's main period of power began in 1540.
