The correct option is A 1530
Humayun ascended the throne in 1530. Babur died and Humayun ascended to the throne on 26 December 1530 as the
second emperor of the Mughal dynasty. He faced bitter rivalry from his
brothers, and also faced threat from other rulers such as Sultan Bahadur
and Sher Shah Suri (Sher Khan). His half-brother Kamran treacherously
took the Punjab and the Indus Valley.
