Now, let`s break down the options:
Option 2 includes Meghalaya, Tripura, Manipur, and Mizoram. While Meghalaya, Tripura, and Mizoram are correct, Manipur is not covered under the Sixth Schedule.
Option 3 includes Assam, Manipur, Meghalaya, and Tripura. While Assam, Meghalaya, and Tripura are covered under the Sixth Schedule, Manipur is not.
Option 4 includes Manipur, Meghalaya, Tripura, and Arunachal Pradesh. While Meghalaya, Tripura, and Manipur are part of the Sixth Schedule, Arunachal Pradesh is not.
