Correct option is B
The correct answer is option (b) Teesta
Explanation
The Gangetic plain is the largest and most fertile part of the northern plain in India, stretching from the western to the eastern part of the country. It is formed by the deposition of alluvial soil by the Ganga and its tributaries. The Gangetic plain lies between the Ghaghara River (which forms the western boundary) and the Teesta River (which forms the eastern boundary).
The Teesta River flows through Sikkim and West Bengal before entering Bangladesh, and its basin is an important part of the eastern stretch of the Gangetic plain. The Gangetic plain is home to numerous important cities, including Kolkata, Patna, and Varanasi, and it is crucial for the agricultural activities of the region.

The Gangetic plain is the largest part of the northern plain in India, known for its fertility and significant agricultural productivity.
The Ghaghara River forms the western boundary of the Gangetic plain, while the Teesta River marks its eastern boundary.
The Teesta River is a major river in Sikkim and West Bengal, and it flows into Bangladesh.
The Gangetic plain is characterized by its alluvial soil, which is highly fertile and supports extensive rice, wheat, and sugarcane cultivation.
This region includes important geographical subdivisions like the Brahmaputra Plain and the Punjab Plain.
Additional Knowledge
Teesta: The Teesta River is an important river that flows through Sikkim and West Bengal in India before entering Bangladesh. The Teesta Basin is part of the eastern stretch of the Gangetic plain, which is crucial for its agriculture. The river has significant cultural and economic importance, especially in the context of water sharing between India and Bangladesh.
Damodar: The Damodar River is located primarily in Jharkhand and West Bengal, and while it plays an important role in the region, it does not define the boundary of the Gangetic plain. The Damodar is an important tributary of the Hooghly River but lies further south than the boundary formed by the Teesta.
Swarnarikha: The Swarnarikha River is a smaller river in the region but does not form a boundary of the Gangetic plain. The Teesta River plays a much more significant role in the region's geography.
Mahanadi: The Mahanadi River flows through Chhattisgarh and Odisha and is part of the Eastern Ghats region. It does not form the boundary of the Gangetic plain either.
