The correct answer is: c) Ahom Dynasty.
The Ahoms were a Shan people who migrated from present-day Myanmar to Assam in the 13th century. They ruled Assam for over 600 years, until they were overthrown by the British in the 19th century.
The Ahoms left behind a rich legacy of inscriptions, which are important sources for understanding the history of Assam. These inscriptions provide information on the Ahom kings, their wars, their administration, and their religion.
The Varman Dynasty was a Hindu dynasty that ruled Assam from the 4th to the 12th centuries. The Pala Dynasty was a Buddhist dynasty that ruled Bengal from the 8th to the 12th centuries. The Mlechchha Dynasty was a non-Aryan dynasty that ruled Assam from the 7th to the 9th centuries.
The inscriptions of the Ahom Dynasty are particularly valuable because they provide information on a period of Assamese history that is not well-documented in other sources.
