Solution
The correct option is A Bhangar The right answer is Bhangar.
Bhangar plains are upland, and consist of older alluvial soil. Bhangar areas are less prone to flooding but are usually more sandy and less fertile as well.
Khadar plains are low lying and consist of new alluvial deposits and are often very fertile.
The rivers, after descending from the mountains deposit pebbles in a narrow belt of about 8 to 16km in width lying parallel to the slopes of the Shiwaliks. It is known as Bhabar. All the streams disappear in this bhabar belt.
South of Bhabar belt, the stream and rivers re-emerge and create a wet, swampy and marshy region known as Terai.
