The correct answer is: All of the above.
Manipur is a state in northeastern India. It is one of the eight states that are officially designated as “tribal states”. The term “tribal state” refers to a state with a significant proportion of tribal people. According to the 2011 census, 32.8% of Manipur’s population belongs to scheduled tribes. Scheduled tribes are indigenous peoples who are considered to be socially and economically backward. They are entitled to certain benefits and protections under the Indian Constitution.
In addition to scheduled tribes, Manipur also has a significant proportion of scheduled castes and other backward classes. Scheduled castes are groups of people who have been historically discriminated against on the basis of their caste. They are also entitled to certain benefits and protections under the Indian Constitution. Other backward classes are groups of people who are considered to be socially and educationally backward. They are also entitled to certain benefits and protections under the Indian Constitution.
The presence of a significant proportion of scheduled tribes, scheduled castes, and other backward classes in Manipur has had a major impact on the state’s social, economic, and political development. These groups have often been marginalized and excluded from mainstream society. However, they have also played a significant role in the state’s struggle for autonomy and self-determination.
