What is the major river-related effect of the general slope of the Deccan Plateau?

Correct answer: Many rivers flow eastward into the Bay of Bengal

Option D is correct because the Deccan Plateau has a broad general slope toward the east and south-east. As a result, major peninsular rivers such as the Godavari, Krishna, and Cauvery generally move eastward and ultimately drain into the Bay of Bengal, often forming deltas near their mouths. The word “many” is important: it does not claim that every river follows exactly the same course. Some rivers, including the Narmada and Tapi, flow west through rift valleys into the Arabian Sea. Therefore D states the general pattern without making an absolute claim.
