Assertion the plains along the bay of Bengal a white and label reason ...
Explanation:

- Assertion (A): The plains along the Bay of Bengal are white.
- Reason (R): This is due to the deposition of sediment by rivers like the Ganga and Brahmaputra, resulting in fertile alluvial plains suitable for agriculture known as the Gangetic plains.
Evaluation:

- Option A: Both A and R are correct, and R is the correct explanation of A.
Reasoning:

The assertion and reason are both correct. The white color of the plains along the Bay of Bengal is due to the deposition of sediment carried by rivers like the Ganga and Brahmaputra. These rivers bring nutrient-rich sediment from the Himalayas and deposit it in the plains, making the soil fertile and suitable for agriculture. This process, known as alluvial deposition, has led to the formation of the Gangetic plains, one of the most fertile regions in India. Therefore, the reason provided explains why the plains along the Bay of Bengal are white, making option A the correct choice.

Question No. 53 to 58 are based on the given text. Read the text carefully and answer the questions:The northern plain has been formed by the interplay of the three major river systems. This plain is formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 km long and 240 to 320 km broad, is a densely populated physiographic division. With a rich soil cover combined with an adequate water supply and favourable climate it is agriculturally a productive part of India The Northern Plain is broadly divided into three sections. The Western part of the Northern Plain is referred to as the Punjab Plains. Formed by the Indus and its tributaries, the larger part of this plain lies in Pakistan. The Indus and its tributaries - the Jhelum, the Chenab, the Ravi, the Beas and the Satluj originate in the Himalaya. This section of the plain is dominated by the doabs.The Ganga plain extends between Ghaggar and Teesta rivers. It is spread over the states of North India, Haryana, Delhi, U.P., Bihar, partly Jharkhand and West Bengal to its East, particularly in Assam lies the Brahmaputra plain. The northern plains are generally described as flat land with no variations in its relief. It is not true. These vast plains also have diverse relief features. According to the variations in relief features, the Northern plains can be divided into four regions. The rivers, after descending from the mountains deposit pebbles in a narrow belt of about 8 to 16 km 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 this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region known as terai. This was a thickly forested region full of wildlife. The forests have been cleared to create agricultural land and to settle migrants from Pakistan after partition.Q.Assertion (
