The correct answer is: Burma.
The Kabaw Valley is a valley in the Chin Hills of Myanmar (Burma) and India’s northeastern state of Manipur. It is a disputed territory between the two countries. The valley was part of Manipur until it was annexed by Burma in 1885. The Burmese government has since claimed the valley as part of its territory, but the Indian government has refused to recognize this claim. The valley is a strategically important region, as it lies on the main route between India and Burma. The valley is also home to a number of ethnic groups, including the Nagas and the Kukis. These groups have been fighting for independence from both India and Burma for many years.
The other options are incorrect because:
- Tripura is a state in northeastern India. It is not a disputed territory between Manipur and any other country.
- China is a neighboring country of both Manipur and Burma. However, the Kabaw Valley is not a disputed territory between China and either of these countries.
- Assam is a state in northeastern India. It is not a disputed territory between Manipur and any other country.
