Dimapur
Kaziranga
Tezpur
Jorhat
Answer is Right!
Answer is Wrong!
The correct answer is: a) Dimapur.
The Kachari kingdom flourished in the region of Dimapur, which is now in the state of Nagaland in India. The Kachari people were an ethnic group that originated in the Brahmaputra Valley. They were a powerful kingdom that ruled over a large area of the region for centuries. The Kachari kingdom was eventually overthrown by the Ahoms in the 16th century.
The other options are incorrect because they are not located in the Brahmaputra Valley. Kaziranga is a national park in Assam, Tezpur is a city in Assam, and Jorhat is a city in Assam.
