Why is Palghat Gap important in the study of the Western Ghats?

Correct answer: It is a major natural opening in the Western Ghats

The Western Ghats form a long mountain chain along the western side of Peninsular India, but the chain is interrupted by important gaps. The Palghat Gap is a broad natural opening between the Nilgiri Hills and the Anaimalai Hills. Since it is lower than the surrounding mountains, it provides a passage between the interior plateau and the coastal region, especially between Kerala and Tamil Nadu. It has therefore influenced transport, settlement, communication, and local climatic conditions. Option A is correct. It is not a Himalayan summit, an Aravalli mineral belt, or a delta of the Ganga Plain. Those descriptions refer to different geographical features and regions.
