The correct answer is: b) Meitei and Pangal (Manipuri Muslims).
The Meitei are the indigenous people of Manipur, and they have a long history of ruling the region. The Pangal are a Muslim minority group in Manipur, and they have also played a significant role in the history of the state.
The Naga and Kuki tribes are also indigenous people of Manipur, but they have traditionally been more independent of the Meitei. The Bengali and Assamese are ethnic groups from neighboring states, and they have had a relatively minor role in the history of Manipur.
The British and Burmese were colonial powers that ruled Manipur for a period of time, but they did not establish dynasties in the state.
