Which river and final outlet pair is correct?

Correct answer: Narmada - Arabian Sea

The direct answer is A: Narmada—Arabian Sea. To solve this, first identify the direction in which each river flows and then identify its final outlet. The Narmada rises in the Amarkantak region and flows mainly westward through a rift valley. It finally enters the Arabian Sea through the Gulf of Khambhat. Option A is therefore the correct river–outlet pair. Option B is wrong because the Kaveri flows eastward and reaches the Bay of Bengal, not the Arabian Sea. Option C is wrong because the Krishna also flows eastward into the Bay of Bengal; it does not reach the Caspian Sea, which is far away in Central Asia. Option D is wrong because the Godavari flows eastward into the Bay of Bengal, not the Red Sea. The important geographical pattern is that most major Peninsular rivers flow eastward, but Narmada and Tapi are famous west-flowing exceptions. Memory cue: Narmada and Tapi go west to the Arabian Sea; Godavari, Krishna and Kaveri go east to the Bay of Bengal.
