The correct answer is: a) Scheduled Tribes.
Mizoram is a state in northeastern India. It is the most populous state in the region, with a population of over 1.1 million people. The majority of Mizoram’s population belongs to the Mizo people, who are a Scheduled Tribe. Scheduled Tribes are indigenous peoples of India who are recognized by the Indian government as being socially and economically disadvantaged. They are entitled to certain benefits and protections under Indian law.
The other options are incorrect. Scheduled Castes are another group of indigenous peoples of India who are recognized by the Indian government as being socially and economically disadvantaged. Other Backward Classes are a group of people who are not considered to be Scheduled Tribes or Scheduled Castes, but who are nevertheless considered to be socially and economically disadvantaged. Minority religious groups are religious groups that are not the majority religion in India.
In conclusion, the majority of Mizoram’s population belongs to the Mizo people, who are a Scheduled Tribe.
