Which of the following rulers ruled Assam in the time of Harsha?

The Correct answer is Option 2 . Key Points During the time of Harsha (606–647 CE), Assam was ruled by the Varman dynasty, specifically Bhaskara varman, who was a contemporary of Harsha. Hence, option 2 is correct. Bhaskaravarman was the most prominent ruler of the Varman dynasty of Assam. He ruled over the kingdom of Kamarupa (modern-day Assam). Bhaskaravarman is known for his alliance with Harsha and played a significant role in the Kannauj Assembly hosted by Harsha. The historical records of Bhaskaravarman are mentioned in Bana Bhatta’s Harshacharita and the Chinese traveler Xuanzang's accounts. Thus, Bhaskaravarman was the ruler of Assam during Harsha’s reign.
