Correct Answer: (a) Rajendra Chola I
Note: The Chola ruler Rajendra Chola I is popularly known as ‘Victor of the Ganges’ or Gangai Konda Chola. Rajendra Chola I, after defeating the Pala dynasty king Mahipala of Bihar and Bengal, assumed the title of ‘Gangai Konda’ due to the state’s boundary from the far south to the Gangetic plains and built a new capital named Gangai Konda Cholapuram.
