SSC GD 2025 PYQ — Question 27

The correct answer is option 2 i.e. The Gandak.

Among the rivers listed, the Gandak does not originate from the Peninsular Plateau. The Gandak River rises in the Himalayas in Nepal and flows into northern India, eventually joining the Ganges. In contrast, rivers like the Son, Chambal, and Mahanadi originate from the Peninsular Plateau, which is made of ancient, hard rocks and has a different drainage pattern. Himalayan rivers generally have steep gradients, perennial flow, and carry more sediments, whereas peninsular rivers are older, seasonal, and slower flowing.
