Correct option is B
Sher Shah Suri was entrusted with the administration of the Parganas of Khawaspur and Sasaram during the lifetime of his father Hasan Khan. These administrative responsibilities helped Sher Shah gain experience in governance and military leadership, which later contributed significantly to his rise as a powerful ruler, ultimately overthrowing the Mughal Emperor Humayun and establishing the Sur Empire.

Sher Shah’s early administrative roles in Khawaspur and Sasaram were crucial in shaping his abilities as an effective leader. His governance reforms, including revenue administration, road construction (like the Grand Trunk Road), and military organization, were inspired by the experience he gained managing these regions. Sasaram, especially, became Sher Shah's stronghold and the place from where he launched his campaigns against the Mughals.
