Which is the most correct reason for the discontinuous structure of the Eastern Ghats?

Correct answer: Many east flowing rivers cut across them

Direct answer: Option A is correct. The Eastern Ghats are discontinuous because several major east-flowing rivers cut through and dissect them on their way to the Bay of Bengal. The reasoning is: the Eastern Ghats lie roughly parallel to the eastern coast; rivers such as the Mahanadi, Godavari, Krishna and Kaveri flow eastward from the interior and cross these hills; erosion and river valleys break the hills into separate sections. Therefore they do not form one continuous wall. Option A gives the correct geomorphic cause. Option B is wrong because the Eastern Ghats are on the eastern side of India, not the western coast. Option C is wrong because they are not coral islands. Option D is wrong because the Eastern Ghats are neither the Himalaya nor India’s highest Himalayan range. The important exam chain is east-flowing rivers plus erosion equals dissected or discontinuous Eastern Ghats.
