The correct answer is: c) 65%.
Arunachal Pradesh has one of the highest proportions of Scheduled Tribe population in India, making up approximately 65% of the total population. The Scheduled Tribes are a group of indigenous peoples who are recognized by the Indian government as being socially and economically disadvantaged. They are entitled to certain benefits and protections under the Indian Constitution.
The Scheduled Tribes in Arunachal Pradesh are a diverse group, speaking over 20 different languages. They are predominantly engaged in agriculture, hunting, and gathering. The state government has implemented a number of programs to improve the lives of the Scheduled Tribes, including providing access to education, healthcare, and employment opportunities.
The other options are incorrect because they do not reflect the actual proportion of Scheduled Tribe population in Arunachal Pradesh. Option a) is incorrect because it is too low. Option b) is incorrect because it is too high. Option d) is incorrect because it is not a realistic estimate.
I hope this helps!
