The correct answer is: a) Allied forces fighting against Japan.
Arunachal Pradesh is a state in northeastern India. It is bordered by Bhutan to the west, China to the north and east, Nagaland to the south, and Assam to the southwest. The state has a population of over 1.3 million people and its capital is Itanagar.
During World War II, Arunachal Pradesh was a strategic location for the Allied forces fighting against Japan. The Japanese army invaded Burma in 1942 and advanced towards India. The Allied forces were determined to stop the Japanese advance and they established a series of defensive positions in Arunachal Pradesh. The Battle of Imphal was fought in this region in 1944 and it was a major turning point in the war. The Allied forces were victorious and they pushed the Japanese back into Burma.
The other options are incorrect because:
- Tibetan refugees did not use Arunachal Pradesh as a strategic location during World War II.
- Indian independence activists did not use Arunachal Pradesh as a strategic location during World War II.
- British tea plantations were not located in Arunachal Pradesh during World War II.
