Correct Answer: B — Cherrapunji lies on the windward side of the Khasi hills and receives rainfall from the Bay of Bengal branch of monsoon, while Shillong lies on the leeward side forming a rain shadow area.
Explanation:
Cherrapunji lies on the windward side of the Khasi Hills, directly exposed to moisture-laden winds from the Bay of Bengal branch of the southwest monsoon, causing extremely heavy orographic rainfall. Shillong, on the leeward side, lies in the rain shadow area and receives significantly less rainfall.
