Step 1: Understanding tribal area administration.
The Constitution of India provides special administrative arrangements for tribal areas to preserve their culture, customs, and unique identity. These areas require different governance structures to safeguard their traditional practices.
Step 2: Constitutional provision.
The Sixth Schedule of the Constitution contains provisions for the administration of tribal areas, particularly in the northeastern states such as Assam, Meghalaya, Tripura, and Mizoram. It provides for Autonomous District Councils with legislative, judicial, and administrative powers.
Step 3: Why other options are incorrect.
The Fifth Schedule deals with the administration of Scheduled Areas in other parts of India but not the specific tribal autonomous structures of the Northeast. The Seventh Schedule deals with the division of powers between Union and States. The Ninth Schedule contains laws protected from judicial review.
Step 4: Conclusion.
Therefore, the correct answer is the Sixth Schedule, which provides a detailed framework for tribal area administration in the Northeastern region.
