Which option correctly matches a local belt of plains with its feature?

Correct answer: भाबर / कंकड़-पत्थर के निक्षेप / Bhabar / pebble and gravel deposits

The direct answer is A: Bhabar consists of pebble and gravel deposits. Along the Himalayan foothills, rivers come down from steep slopes carrying large stones, pebbles, and coarse sediments. These materials are deposited in a porous belt called Bhabar. Because the spaces between the pebbles are large, streams may disappear underground there and reappear farther south in the Terai. Reasoning step by step: identify the belt at the Himalayan foothills; remember that fast streams deposit coarse material first; match coarse pebbles and gravel with Bhabar; therefore A is correct. Option A accurately pairs Bhabar with coarse deposits. Option B is wrong because Terai is a marshy, damp belt, not a belt of coral islands. Option C is wrong because Khadar means newer alluvium deposited by present rivers, whereas old alluvium is Bhangar. Option D is wrong because Bhangar is old alluvium, while new alluvium is Khadar. Memory cue: “Bhabar has big stones; Terai is wet; Khadar is new; Bhangar is old.”
