Which of the following tree species is/are found on Himalayas ? 1. Oak 2. Rhododendron 3. Rosewood Select the correct answer using the code given below :

The vegetation of the Himalayas varies according to altitude, ranging from tropical to alpine types. Oak and Rhododendron are characteristic species of this region:

• Oak: These are dominant species in the temperate forests of the Himalayas, typically found at altitudes between 1,500 and 3,300 meters.
• Rhododendron: These are widely distributed across the Himalayan range, especially in the Eastern Himalayas, occurring in temperate, sub-alpine, and alpine zones.
• Rosewood: This is a tropical hardwood tree (Dalbergia latifolia) primarily found in the tropical evergreen forests of the Western Ghats, Andaman and Nicobar Islands, and parts of Northeast India, but it is not a native species of the Himalayan mountain ecosystem.

Therefore, only Oak and Rhododendron are found in the Himalayas, making Option D the correct answer.
