Bangar soils are less prone to floods. - This statement is correct. Bangar represents the older alluvium in the riverine system of the northern plains and lies above the flood plains. It is not regularly replenished by floodwaters, hence, less prone to floods.
Bangar soils are nothing but new alluvial soils. - This statement is incorrect. It's actually the Khadar soils that are the newer or young alluvial soils, replenished by annual floods, making them more fertile. Bangar, in contrast, consists of older alluvium.
Bangar soils are more fertile than Khadar soils. - This statement is incorrect. Khadar soils, being newer alluvium replenished by annual floods, are more fertile than Bangar soils, which are older and have been leached due to the absence of such replenishment.
Khadar plains are those that are low-lying next to a river. - This statement is correct. Khadar lands are newer alluvial plains found in the lower areas and are prone to flooding, which also makes them more fertile due to the newer sediments deposited by river floods.

Explanation:
Bangar and Khadar are two types of alluvial soils found in the Indo-Gangetic plain, which is a fertile region due to the deposition of sediment-rich alluvium from the Himalayas. Let's examine each statement:
1. Bangar soils are less prone to floods: This statement is incorrect. Bangar soils are older alluvial soils that are situated on elevated terraces above the floodplains. They are not immune to floods and can be affected by them.
2. Bangar soils are nothing but new alluvial soils: This statement is incorrect. Bangar soils are older alluvial soils that have been deposited on the river terraces over a long period of time. Khadar soils, on the other hand, are newer alluvial soils that are deposited on the floodplains during floods.
3. Bangar soils are more fertile than Khadar soils: This statement is incorrect. Khadar soils are generally more fertile than Bangar soils due to their higher nutrient content and better water retention capacity.
4. Khadar plains are those that are low-lying next to a river: This statement is correct. Khadar plains are low-lying areas along the riverbanks that are regularly flooded by the river. They are characterized by newer alluvial soils that are deposited during floods.
Therefore, the correct answer is option B, which states that statements 2 and 3 are incorrect.
