The example of the Luni river complicates which idea about Indian drainage?

Correct answer: Some rivers end in inland basins

Direct answer: B, some rivers end in inland basins. Drainage means the way river water flows and where it finally ends. Many Indian rivers flow to the sea, but this is not true for every river. The Luni flows through the dry region of Rajasthan. Much of its water is lost by evaporation or enters inland depressions and salt marshes such as the Rann of Kachchh rather than forming a permanent route to the sea. Therefore it shows that India also has inland drainage. Option A is wrong because “all” is too absolute. Option B is correct because it describes inland drainage. Option C is wrong because Luni does not rise in the Himalayas; it rises in the Aravalli region. Option D is wrong because not every river forms a delta. Memory cue: Luni means limited inland drainage.
