Answer

C

Explanation

Sea buckthorn (Hippophae) is encouraged by the Government of India because: (1) It helps control soil erosion and prevent desertification due to its extensive root system. (3) It has high nutritional value (rich in vitamins C, E, and fatty acids) and is well-adapted to cold high-altitude areas. It is NOT a rich source of biodiesel (statement 2) and its timber is NOT of great commercial value (statement 4). The question specifically asks why government encourages it — the answer relates to its ecological and nutritional benefits.
