Select the correct answer using the code given below:

• A. 1 only
• B. 2 and 3 only
• C. 3 only
• D. 1 and 3 only

Answer 1

The correct option is C 3 only

Explanation:

• Statement 1 is incorrect: Bhabar is a narrow belt ranging between 8-10 km parallel to the Shivalik foothills at the break-up of the slope. As a result of this, the streams and rivers coming from the mountains deposit heavy materials of rocks and boulders, and at times, disappear in this zone
• statement 2 is incorrect: South of the Bhabar is the Terai belt, with an approximate width of 10-20 km where most of the streams and rivers re-emerge without having any properly demarcated channel, thereby, creating marshy and swampy conditions are known as the Tarai. This has a luxurious growth of natural vegetation and houses varied wildlife
• Statement 3 is correct: The south of Tarai is a belt consisting of old and new alluvial deposits known as the Bhangar and Khadar respectively. These plains have characteristic features of the mature stage of fluvial erosional and depositional landforms such as sand bars, meanders, oxbow lakes, and braided channels. The Brahmaputra plains are known for their riverine islands and sandbars. Most of these areas are subjected to periodic floods and shifting river courses forming braided streams.
