Which option gives the correct comparative difference between Bhabar and Terai?

Correct answer: Bhabar is pebbly foothill and Terai is wet marshy region

Direct answer: Option C is correct. Bhabar and Terai are two different belts at the Himalayan foothills. Bhabar is a narrow, coarse, pebbly belt formed by material brought down by streams from the mountains. Its porous surface allows streams to disappear underground. South of it, the Terai is a low, wet and marshy belt where those underground streams re-emerge. Option C gives both parts in the correct order, so it works. Option A reverses the two characteristics: wet marshy describes Terai, while pebbly foothill describes Bhabar. Option B is wrong because neither belt is a marine or volcanic region in this comparison. Option D is wrong because Bhabar and Terai are foothill belts, not peaks of the high Himadri range. The reasoning is based on material and water movement, not just location: coarse pebbles and disappearing streams identify Bhabar; moisture and reappearing streams identify Terai. Memory cue: “Bhabar is pebbly; Terai is soggy.”
