The correct answer is: a) Kamarupa.
Bhishmaknagar is an archaeological site located in the Sonitpur district of Assam, India. It is believed to be the capital of the ancient Kamarupa kingdom. The site was first excavated in the early 20th century, and has since yielded a number of important artifacts, including coins, pottery, and sculptures.
The Kamarupa kingdom was one of the most powerful kingdoms in eastern India during the early medieval period. It was founded in the 7th century by the Varman dynasty, and reached its peak under the reign of Bhaskaravarman (600-650 CE). The kingdom was eventually conquered by the Pala dynasty in the 9th century.
The Bhismaknagar site is a valuable source of information about the history and culture of the Kamarupa kingdom. It is a reminder of the region’s rich and complex past.
The other options are incorrect because:
- The Ahom kingdom was a later kingdom that ruled over Assam from the 13th to the 19th centuries.
- The Pala kingdom was a contemporary of the Kamarupa kingdom, but it was located in Bengal.
- The Chutiya kingdom was a smaller kingdom that existed in Assam in the 15th and 16th centuries.
