The correct option is (c).
Explanation
The Northern Plains of India are formed by the depositional work of three major river systems-the Indus, the Ganga, and the Brahmaputra-along with their tributaries. Geographically, the plains are divided into three major sections based on the river systems that drain them.
Statement-wise Analysis:
- Statement 1 is Correct: The western part of the Northern Plain is referred to as the Punjab Plains. It is formed by the Indus and its tributaries (the Jhelum, the Chenab, the Ravi, the Beas, and the Satluj). A significant characteristic of this region is the dominance of doabs (fertile land lying between two converging rivers).
- Statement 2 is Incorrect: The Ganga plain extends between the Ghaggar and Teesta rivers. It covers the states of Haryana, Delhi, Uttar Pradesh, Bihar, partly Jharkhand, and West Bengal. The region between the Indus and the Satluj is part of the Punjab Plains, not the Ganga Plain.
- Statement 3 is Correct: The Brahmaputra plain forms the eastern section of the Northern Plains. It lies principally in the state of Assam, formed by the Brahmaputra river and its tributaries.
Key Takeaway:
The Northern Plains are longitudinally divided into the Punjab Plains (West, dominated by doabs), the Ganga Plains (Central, between Ghaggar and Teesta), and the Brahmaputra Plains (East, primarily in Assam).
