The correct option is A Rajasmand
Located 84 kms north of Udaipur in the wilderness in the Rajasmand district, Kumbhalgarh is the second most important fort after Chittorgarh in the Mewar region. Cradled in the Aravali Ranges the fort was built in the 15th century AD by Rana Kumbha. The inaccessibility and hostility of the topography lends a semblance of invincibility to the fort. It served the rulers of Mewar as a refuge in times of strife. The fort also served as refuge to King Udai of Mewar in his early childhood.
