Which is the longest peninsular river?

Correct answer: Godavari

The direct answer is B: Godavari. Among the major rivers of the Indian Peninsular drainage system, the Godavari is the longest, with a course of roughly 1,465 km, and it flows eastward to the Bay of Bengal. It is therefore often called the “Dakshin Ganga,” meaning the Ganga of the South. Option B is correct because Godavari is the accepted school-geography answer for the longest Peninsular river. Option A, Kaveri, is an important east-flowing river and forms a delta, but it is considerably shorter than Godavari. Option C, Tapi, is a major west-flowing river that enters the Arabian Sea through an estuary; it is not the longest Peninsular river. Option D, Luni, is a shorter, largely seasonal river of the western dry region and does not reach the sea in the same way as the major east-flowing rivers. The exam memory link is simple: Godavari = longest Peninsular river = Dakshin Ganga. Do not confuse its long course with the shorter Kaveri or west-flowing Tapi.
