What is a simple proof of the eastward slope of the Deccan Plateau?

Correct answer: Many rivers fall into the Bay of Bengal

Direct answer: Option A, many rivers enter the Bay of Bengal. A plateau surface slopes downward, and rivers generally flow from higher land toward lower land. The Godavari, Krishna, Kaveri, and Mahanadi mostly flow eastward and drain into the Bay of Bengal. This river pattern gives simple evidence of the Deccan Plateau’s eastward slope. Option A is correct. Option B is wrong because not all rivers enter the Arabian Sea; west-flowing rivers are fewer. Option C is wrong because many plateau rivers rise in the plateau or Western Ghats, not the Himalayas. Option D is wrong because several important rivers cross the plateau. Cue: river flow reveals land slope.
