Q1. Which of the following is the largest inhabited riverine island in the world?
Explanation
Majuli, located in the Brahmaputra River in Assam, is commonly cited in Indian exam usage as the world's largest inhabited riverine island. Umananda is also in the Brahmaputra near Guwahati, but it is a much smaller island. Marajo is a very large island in Brazil, yet the official CET framing identifies Majuli for this inhabited riverine-island fact. Doab is not an island at all; it means the land lying between two rivers. Therefore Majuli matches the question's required description.
