B. Khadar and Bhumiya
C. Bhumiya and Banger
D. None of these

Answer 1

Hint: The northern plains of India are very important from the agricultural point of view because the soil's fertility is maintained every year due to the availability of alluvial soil. States like Punjab and Haryana boost wheat cultivation due to the availability of alluvial soil. Alluvial soil is rich in minerals essential for cultivation.

Complete answer:
The plain of northern india is made up of alluvial deposits brought by the rivers sindhu, ganga and brahmaputra. In the north to south direction these plains can be divided into three parts like bhabhar, tarai and alluvial plains. The alluvial plain is further divided into two parts - bangar and khadar. Old and new alluvial respectively are called bangar and khadar because of bangar formed by old alluvial and new khadar formed by new alluvial in india. It is also known as the Northern Plain of India.
Bangar is the high part of the plains where the flood water can not reach. It is constructed from old alluvial and there is more quantity of pebbles and sand. Large pebble stones are found here where the water flows in a calm nature.
Khadar is made of a new alluvial. The floods bring new soil every year. This region is also known as the Kutch region or flood plains. In this erosion occurs towards the river. Here the size of the pebble stones gets smaller and the water flows at a faster rate.
So, the correct answer is option A.

Note: Khadar and bangar region is important for indian agriculture. Punjab and haryana states are the result of the Khadar region where rice is cultivated most. Record production of wheat and rice in India depends on these regions.
