Correct Option: C

The Kaivarta rebellion occurred in Bengal during the reign of Mahipala II. Varendra rebellion occurred during the reign of the pala emperor Mahipala II (c 1075-1080 AD) and resulted in his death and the loss of Varendra (north Bengal) to the Kaivarta chief divya. Mahipala II is said to have imprisoned his two brothers, Xurapala and Ramapala out of suspicion that Ramapala would capture royal power. The possibility of a dynastic trouble arising out of the ambition of a capable younger brother cannot be altogether ruled out.
