The correct answer is: Sixth.
The Sixth Schedule of the Constitution of India lists the tribal areas of Assam, Meghalaya, Tripura, and Mizoram. It provides for a special administrative arrangement for these areas, which are governed by their own autonomous councils. The Sixth Schedule also lists the central laws and other laws that are applicable to these areas.
On August 5, 2019, the Government of India passed the Jammu and Kashmir Reorganisation Act, 2019. This Act dissolved the State of Jammu and Kashmir and created two Union Territories: Jammu and Kashmir and Ladakh. The Act also amended the Sixth Schedule of the Constitution to include the Union Territory of Ladakh.
As a result of the amendment, all central laws and other laws in the Sixth Schedule of the Constitution which were applied in the State of Jammu and Kashmir, are now applicable to the Union Territories of Jammu and Kashmir and Ladakh.
The other options are incorrect because:
- The Fifth Schedule of the Constitution lists the tribal areas of Andhra Pradesh, Telangana, Karnataka, Kerala, and Madhya Pradesh.
- The Eighth Schedule of the Constitution lists the 22 scheduled languages of India.
- The Ninth Schedule of the Constitution lists certain laws that are not subject to judicial review.
