The discontinuous nature of which Ghats can be understood from Mahendragiri, Shevaroy, and Javadi Hills?

Correct answer: Eastern Ghats

The correct answer is A, the Eastern Ghats. Mahendragiri, Shevaroy, and Javadi are separated hill sections belonging to the broader Eastern Ghats system. Unlike the relatively continuous Western Ghats, the Eastern Ghats are discontinuous because major rivers such as the Mahanadi, Godavari, Krishna, and Kaveri have cut across them on their way to the Bay of Bengal. This river dissection produces a broken chain of hills rather than one uninterrupted wall. The Aravalli and Karakoram are separate mountain systems, while the Western Ghats do not illustrate the specific discontinuity described in the question.
