The state of Meghalaya was carved out of Assam in the year 1972. Prior to this, Meghalaya was part of Assam and was known as the 'United Khasi and Jaintia Hills' and 'Garo Hills'. The demand for a separate state for the Khasi, Jaintia, and Garo tribes led to its creation. The state was formally established on January 21, 1972, after successfully attaining statehood following negotiations and constitutional amendments.
Thus, the correct option is Meghalaya.
Meghalaya was carved out of Assam in 1972, becoming an autonomous state. The state's formation was a result of the demands for autonomy by the Khasi, Garo, and Jaintia tribes, which were previously part of Assam. This was a significant step in recognizing the cultural and administrative aspirations of these tribal communities.
