Explanation: The Northern Plain of India is a significant geographical feature that plays a crucial role in the country's agriculture and economy. It is a vast alluvial plain that stretches from the Indus River in the west to the Brahmaputra River in the east, covering a large part of northern India. The plain is divided into three main sections: the Punjab Plains, the Ganga Plains, and the Brahmaputra Plains.
The Punjab Plains are located in the western part of the Northern Plain and are formed by the alluvial deposits of the Indus River and its tributaries. This region is known for its fertile soil and is a major agricultural area, particularly for wheat and cotton production.
The Ganga Plains, also known as the Upper Ganga Plains, are located in the central part of the Northern Plain and are formed by the alluvial deposits of the Ganga River and its tributaries. This region is one of the most densely populated areas in India and is known for its rich agricultural productivity, with crops such as rice, wheat, and sugarcane being widely cultivated.
The Brahmaputra Plains are located in the eastern part of the Northern Plain and are formed by the alluvial deposits of the Brahmaputra River and its tributaries. This region is characterized by its flat terrain and fertile soil, making it suitable for agriculture, particularly for rice cultivation.
Each of these sections of the Northern Plain is characterized by its own unique geographical features and is formed by the alluvial deposits of the respective rivers. The alluvial nature of the soil in these plains makes them highly fertile and suitable for agriculture, which is why they are often referred to as the "breadbasket" of India.
It is important to note that the Northern Plain is not divided by state or regional names, but rather by the sections formed by the alluvial deposits of the major rivers. Therefore, options that list regions or states (such as Haryana, Punjab, and Delhi) or geological terms (such as Bhangar, Kankar, and Bhabar) are incorrect.
In conclusion, the correct answer is (B) Punjab Plains, Ganga Plains, and Brahmaputra Plains, as these are the recognized sections of the Northern Plain of India, each formed by the alluvial deposits of the Indus, Ganga, and Brahmaputra rivers, respectively.
