1 and 3 only

D

1, 2, 3 and 4

Correct Answer: Option C

Explanation

1. Statement 1 is correct. Sea buckthorn (Hippophae spp.) has an extensive root system that effectively binds soil. This makes it valuable for controlling soil erosion, stabilizing slopes, and preventing desertification, particularly in fragile ecosystems. 2. Statement 2 is incorrect. While research into various plant oils for biodiesel exists, sea buckthorn is not primarily considered a rich source of biodiesel compared to other crops like Jatropha or soybean. Its oil is more valued for nutritional and medicinal purposes. 3. Statement 3 is correct. Sea buckthorn berries are highly nutritious, packed with vitamins (especially Vitamin C), antioxidants, amino acids, and fatty acids. The plant is known for its hardiness and is well-adapted to survive in harsh environmental conditions, including the cold areas of high altitudes found in the Himalayas. 4. Statement 4 is incorrect. Sea buckthorn is typically a shrub or small tree. Its timber is generally not large enough or of sufficient quality to have great commercial value compared to established timber-producing trees.
