What is the reason for the dominance of east-flowing rivers in the Deccan Plateau?

Correct answer: The plateau generally slopes east and south-east

Option A is correct because the Deccan Plateau has a general gradient toward the east and south-east. Rivers such as the Godavari, Krishna, and Cauvery follow this broad slope and drain into the Bay of Bengal, often forming deltas near their mouths. The rule is general rather than absolute: the Narmada and Tapi flow westward through structural rift valleys, showing that local geology can alter drainage direction. Option B reverses the main regional slope, C is false because many Deccan rivers rise within or near the peninsula, and D ignores the clear relief that guides river flow.
