What is the correct river association of Jog Falls?

Correct answer: Sharavathi River

The direct answer is A: Jog Falls is associated with the Sharavathi River. A waterfall forms where river water descends steeply over a resistant rock step, escarpment, or other sharp height difference. Jog Falls is a major waterfall in Karnataka on the Sharavathi River. The reasoning is: identify the named waterfall; recall its river association; match Jog Falls with Sharavathi. Option A is correct because Sharavathi creates the famous Jog Falls, also called Gerosoppa Falls, in the Western Ghats region. Option B, the Ganga, is wrong because Jog Falls is not on the Ganga; the Ganga is a major Himalayan river system of northern India. Option C, the Brahmaputra, is wrong because it is another Himalayan river flowing through the north-east, not the river connected with Jog Falls. Option D, the Jhelum, is wrong because Jhelum is associated with the Kashmir region and does not form Jog Falls. The question tests a factual river-and-waterfall pair, not a general definition of waterfalls. Memory cue: Jog Falls—Sharavathi; keep this pair together for map and matching questions.
