Which evidence is most suitable to prove the discontinuous nature of the Eastern Ghats?

Rivers like Mahanadi, Godavari, Krishna, and Cauvery cut them

The governing concept is how river erosion and incision create gaps in a mountain chain. The Eastern Ghats are not one unbroken wall because several major east-flowing peninsular rivers cross them, including the Mahanadi, Godavari, Krishna and Cauvery. Their courses divide the range into separate sections, making option C the strongest direct evidence of discontinuity. Connection with the Himalayas is not the defining fact and is geographically misleading. The Thar Desert is a separate arid region, and the Eastern Ghats are not completely snow-covered. The conclusion follows from physical observation: if large rivers cut through a range at multiple places, the range appears broken rather than continuous.
