The correct option is A Viren
In the Chola kingdom, a village was called a Tehsil or a Kurram, and a group of Tehsils or Kurrams together formed a Nadu. A bunch of Nadus together formed a Kottam. When a few Kottams were combined, it formed provinces called Mandalams. There were six Mandalams within the kingdom, and these were governed by governors chosen from members of the royal family. As Viren is a member of the royal family, he would be made the governor of the Mandalam.
