The correct option is D Humayun
Humayun was completely defeated by Sher Shah Suri in the battle of Kannauj. In May 1540 , the armies met once again opposite Kannauj and the Mughal Empire was put to an end for a while. At Kannauj , the Afghans were able to scatter the Mughals army, which mere by panic, fled in confusion. Humayun again escaped from the battle field and from that day, for next 15 years he lived like a wanderer.
