Which organization documents and promotes the cultural heritage of Assam’s tribes?

The correct answer is: c) Tribal Research Institute, Assam.

The Tribal Research Institute, Assam (TRI) is a state government organization that was established in 1950 to document and promote the cultural heritage of Assam’s tribes. The TRI has a museum, a library, and a research center. The museum has a collection of artifacts from Assam’s tribes, including clothes, jewelry, weapons, and musical instruments. The library has a collection of books, journals, and other materials on Assam’s tribes. The research center conducts research on Assam’s tribes and publishes its findings in books and journals.

The other options are incorrect because:

• The Directorate of Cultural Affairs, Assam is a government organization that is responsible for promoting culture in Assam. However, it does not have a specific focus on Assam’s tribes.
• The Indira Gandhi Rashtriya Manav Sangrahalaya is a national museum in New Delhi that has a collection of artifacts from all over India. It does not have a specific focus on Assam’s tribes.
• The Assam State Museum is a state museum in Guwahati that has a collection of artifacts from all over Assam. It does not have a specific focus on Assam’s tribes.
