The correct option is (c).
Explanation
The Himadri, also known as the Great or Inner Himalayas, is the northernmost longitudinal range of the Himalayan mountain system.
- Statement 1 is Correct: The Himadri is the most continuous range consisting of the loftiest peaks with an average height of 6,000 metres. It contains all the prominent Himalayan peaks, such as Mount Everest, Kanchenjunga, Makalu, and Dhaulagiri.
- Statement 2 is Incorrect: The range is perennially snow-bound due to its high altitude. It remains covered in snow throughout the year, not just during the winter months. The core of this part of the Himalayas is composed of granite.
- Statement 3 is Correct: A number of glaciers descend from this range, which act as the source for many major rivers. Examples include the Gangotri and Yamunotri glaciers.
Key Takeaway: The Himadri (Great Himalayas) is characterized by its continuity, extreme altitude, perennial snow cover, and being the zone of the highest peaks and major glaciers.
