The correct option is D Tanjavuru
The Cholas were once feudatories of the Pallavas. They later rose to power when the Pallavas weakened. The real victory for Vijayalaya was when he conquered Tanjavuru and established it as the capital of the Medieval Chola Empire. It was Aditya I who brought an end to the Pallavas and established the Cholas as the main power in the region.
