Bhabar is a narrow belt ranging between 8-10 km parallel to the Shiwalik 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. South of the Bhabar is the Tarai 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 known as the Tarai
This has a luxurious growth of natural vegetation and houses a varied wild life. The Terai is crossed by the large perennial Himalayan rivers Yamuna, Ganges, Sarda, Karnali, Narayani and Kosi that have each built alluvial fans covering thousands of square kilometres below their exits from the hills

Explanation:
The Tarai region of the Northern plains is known for its luxurious growth of natural vegetation and varied wildlife population. The reasons for this are as follows:
1. Reemerging rivers from Bhabhar flow in undemarcated channels here, creating marshy and swampy conditions: The Bhabhar region lies at the foot of the Himalayas and consists of porous materials like boulders and pebbles. The rivers flowing through this region disappear underground due to the porous nature of the soil. However, when these rivers reemerge in the Tarai region, they create marshy and swampy conditions, which are ideal for the growth of natural vegetation and support a varied wildlife population.
2. All fertile course load is deposited at Tarai region after rivers reemerge from Bhabar region: The rivers flowing through the Bhabhar region carry a large amount of fertile course load consisting of silt, clay, and other organic matter. When these rivers reemerge in the Tarai region, they deposit all this fertile course load, which helps in the growth of natural vegetation.
3. The Tarai region is crossed by large Himalayan rivers which regularly deposit silt and clay here: The Tarai region is crossed by large Himalayan rivers like the Ganga, Yamuna, and their tributaries. These rivers carry a huge amount of silt and clay from the Himalayas and regularly deposit it in the Tarai region. This deposition of silt and clay helps in the growth of natural vegetation and supports a varied wildlife population.
Therefore, both 1 and 3 are correct, and the correct answer is option D.
