The correct option is D Sher Shah
Humayun became the king of the Mughal dynasty in India after the death of his father, Babur, in 1531 C.E. He faced conflicts with two major powers: Bahadur Shah and Sher Shah. Sher Shah defeated Humayun, who fled India, and ruled for a while.
Akbar was Humayun's son and Shah Jahan his great-grandson.
