Correct Answer: Option A - Indus and its tributaries
The Indus River system is known for forming the Punjab-Haryana plain through its extensive network of tributaries. The name "Punjab" itself means "land of five rivers," referring to the five major tributaries of the Indus: Jhelum, Chenab, Ravi, Beas, and Sutlej.
These tributaries combine to create a vast alluvial plain that covers parts of both Punjab and Haryana states in India, as well as parts of Pakistan. The fertile soil deposited by these rivers has made this region one of the most agriculturally productive areas in the Indian subcontinent.
While the Ganga river system is significant for much of North India, it primarily forms the Indo-Gangetic plain further east. The Brahmaputra river system is more significant in Northeast India, particularly Assam. The Luni and Saraswati river system is primarily associated with the arid regions of Rajasthan and not with the Punjab-Haryana plain.
