Answer: B

Explanation:

The north-eastern plateau of India is an extended part of the peninsular plateau. It is believed that during the origin of the Himalayas, due to the north-east movement of the Indian Plate, it was separated by the formation of a rift valley between the Rajmahal Hills and the Meghalaya Plateau. Later it was covered by alluvium deposited by the river. Today, Meghalaya and the Karbi Anglong Plateau (Assam) are isolated from the main peninsular plateau for this reason. Hence, statement 1 is correct.

Like the Chhotanagpur plateau, the Meghalaya plateau is also a storehouse of minerals like coal, iron, sillimanite, limestone and uranium. Hence, statement 2 is incorrect

Most of the rainfall in the north-eastern plateau region comes from the south-west monsoon. As a result, the Meghalaya plateau has a highly eroded surface. Cherrapunji is a place covered with bare rocks and there is almost no vegetation here. Nokrek is the highest peak of the Meghalaya plateau. Hence, statement 3 is correct.
