Which rivers are helpful examples for calling the Eastern Ghats a discontinuous range?

Correct answer: Mahanadi, Godavari, Krishna and Cauvery

The governing concept is the discontinuous character of the Eastern Ghats. Unlike the more continuous Western Ghats, the Eastern Ghats are interrupted and dissected by major rivers flowing toward the Bay of Bengal. The Mahanadi, Godavari, Krishna and Cauvery cross or cut through different sections of this hill system, so option A is the appropriate answer. The Indus, Jhelum, Chenab and Ravi are mainly associated with the northwestern Himalayan river system, not the Eastern Ghats. Luni, Sabarmati, Mahi and Narmada are linked chiefly with western or central India. Teesta, Dihang, Lohit and Dibang belong largely to the northeastern Himalayan region. Thus the river group in A best explains the range's discontinuity.
