Correct option is D
The correct answer is (d) 2 and 3.
The Barak River, the head stream of the Meghna, rises in the hills of Meghalaya: This statement is incorrect. The Barak River originates in the Manipur Hills in northeastern India, not in the hills of Meghalaya. It flows through Manipur, Mizoram, and Assam before entering Bangladesh, where it eventually becomes the Meghna.
The Ghaggar River does not drain out to the sea and gets lost in the Rajasthan desert: This statement is correct. The Ghaggar River is a seasonal river in northwestern India that flows through Haryana and Punjab and eventually disappears into the sands of the Thar Desert in Rajasthan. It is considered a non-perennial river as it does not reach the sea.
Puthimari and Manas are important tributaries of the Brahmaputra: This statement is correct. Both Puthimari and Manas are significant tributaries of the Brahmaputra River in Assam. The Manas River is particularly important as it forms part of the boundary between Bhutan and India and is known for its rich biodiversity.
