Which Indian geography term is associated with identity or classification “an ancient tableland composed largely of crystalline rocks” and also with “lies south of the Northern Plains”?

Correct Answer: Option A — Peninsular Plateau. Peninsular Plateau is correct because it is an ancient tableland composed largely of crystalline rocks. It is also associated with lies south of the Northern Plains, which provides a second reliable identifying clue. These features are standard physical-geography facts and are useful for map-based and statement-based competitive-exam questions. Why the other options are incorrect: Option B — Thar Desert: It is an arid sandy region also called the Great Indian Desert; this is the specific geographical association of Thar Desert. Option C — Western Coastal Plain: It is a narrow coastal lowland along the Arabian Sea; this is the specific geographical association of Western Coastal Plain. Option D — Eastern Coastal Plain: It is a broad coastal lowland along the Bay of Bengal; this is the specific geographical association of Eastern Coastal Plain. Exam Takeaway: Connect Peninsular Plateau with “an ancient tableland composed largely of crystalline rocks” for quick revision.
