The correct answer is: c) Ahom Dynasty.
The Ahom Dynasty was a Tai-Shan dynasty that ruled the Brahmaputra Valley in northeastern India from the 13th to the 19th centuries. The Ahoms were originally from Yunnan in China, and they migrated to Assam in the 13th century. They established a powerful kingdom that lasted for over 600 years.
The Ahoms were skilled in writing and administration, and they left behind a rich legacy of inscriptions and coins. These inscriptions provide valuable information about the history, culture, and religion of the Ahoms. They also help us to understand the relationship between the Ahoms and the other peoples of Assam.
The Varman Dynasty was a Hindu dynasty that ruled Kamarupa, an ancient kingdom in northeastern India, from the 4th to the 12th centuries. The Varmans were patrons of art and literature, and they left behind a number of temples and inscriptions. However, their inscriptions are not as valuable as the Ahom inscriptions for understanding the history of Assam.
The Pala Dynasty was a Buddhist dynasty that ruled Bengal and Bihar in eastern India from the 8th to the 12th centuries. The Palas were patrons of art and literature, and they left behind a number of temples and inscriptions. However, their inscriptions are not as valuable as the Ahom inscriptions for understanding the history of Assam.
The Mlechchha Dynasty was a non-Aryan dynasty that ruled parts of India from the 6th to the 12th centuries. The Mlechchhas were not patrons of art and literature, and they left behind very few inscriptions. As a result, their inscriptions are not as valuable as the Ahom inscriptions for understanding the history of Assam.
