The correct option is B Prataparudra
Prataparudra was the grandson of Rudramadevi and the last leader
of Kakatiya dynasty. He introduced many administrative reforms in the
state. He was one of the first Telugu kings who defended the Telugu
country from the onslaught of Muslim invaders. It was only after the
death of Prataparudra that Muslims could enter into Telugu lands to rule
the Telugu people.
