(C) Western Himalayas
The passage directly states: "In hill and mountainous regions, people built diversion channels like the 'guls' or 'kuls' of the Western Himalayas for agriculture." This is a direct fact-based MCQ — students must not confuse it with other regional water harvesting methods like khadins/johads (Rajasthan) or inundation channels (Bengal).
