Why are the Eastern Ghats called more discontinuous?

Correct answer: Because many rivers cut them

The direct answer is option A: many rivers cut across the Eastern Ghats. A continuous mountain range would form a more unbroken barrier, but rivers flowing eastward from the interior have eroded valleys and gaps through the Eastern Ghats. Important rivers such as the Mahanadi, Godavari, Krishna, and Kaveri cross or cut parts of this range, making it discontinuous and irregular. Option A is correct because river erosion and river valleys interrupt the hills. Option B is wrong: the Eastern Ghats are not described as submerged in the sea. Option C is wrong: they are not a range made by glaciers; their rocks and landforms have different geological histories. Option D is wrong: coral does not form the Eastern Ghats. The word discontinuous means broken or interrupted, not absent everywhere. Memory cue: Eastern Ghats are broken by east-flowing rivers; Western Ghats are generally more continuous.
