Meghalaya was established as a separate state in 1972, having previously been a part of Assam. Before its formation, the region was known as the 'United Khasi and Jaintia Hills' and 'Garo Hills'. The state's creation was a result of the demand for autonomy by the Khasi, Jaintia, and Garo tribes. Meghalaya officially became a state on January 21, 1972, following negotiations and constitutional amendments.
Therefore, the correct answer is Meghalaya.
