How can Peninsular rivers be distinguished from Himalayan rivers?

Correct answer: They are mostly rain fed and less perennial

Direct answer: Option A is correct. Peninsular rivers generally flow over the older, more stable Peninsular Plateau. Many depend mainly on seasonal monsoon rainfall, so their water volume often falls greatly in the dry season. Consequently, many are less perennial than Himalayan rivers, which receive water from rainfall, snow, and glaciers and are more consistently supplied. Option A gives the useful broad distinction: mostly rain-fed and less perennial. Option B is wrong because Peninsular rivers do not all rise from glaciers. Option C is wrong because they do not all join the Ganga; rivers such as the Mahanadi, Godavari, Krishna, and Kaveri commonly flow east, while Narmada and Tapi flow west. Option D is wrong because they do not all come from Tibet. The comparison is general, not absolute: some Peninsular rivers may have water for much of the year, but their dependence on monsoon is greater. Memory cue: Himalayan rivers—snow and glaciers; Peninsular rivers—old plateau and monsoon.
