a. Himalayas
b. Semi-arid
c. Trans Himalayas
d. North-east

Answer 1

Hint: The Biogeography refers to the geographical distribution of plants and animals. There are 10 bio-geographical Zones in India. Trans-Himalayan Ranges of India constitutes 5.6 per cent of the total geographical area, is located particularly in the northernmost regions of the country like Ladakh, Jammu and Kashmir, North Sikkim and Himachal Pradesh.

Complete answer:
India is one of the rich biodiversity nations amongst the top ten rich biodiversity nations in the world. Biogeographical classification of India is the division of India according to biogeographic characteristics. Biogeography is the study of the distribution of species, organisms, and ecosystems in geographic space and through geological time. There are ten biogeographic regions in India.
- Trans-Himalayan zone
- Himalayan zone
- Desert zone
- Semi Arid region
- Western Ghats
- Deccan plateau
- Gangetic plain
- North east region
- Coastal region
- Andaman and Nicobar islands

Among the given options:
> Himalayas constitute 6.4 per cent of the total geographical area including some of the highest peaks in the world. The Himalayan region makes India one of the richest areas in terms of habitats and species.

> Semi-arid Region constitutes 16.6 per cent of the total geographical area. It is a meeting zone between the desert and the dense forests of Western Ghats.

> The North East Region includes 5.2 per cent of the total geographical area. This region represents the transition zone between the Indian, Indo-Malayan and Indo-Chinese bio-geographical regions and also considered as a meeting point of the Himalayas and peninsular India.

Hence, The correct answer is option (C).

Note: India is a megadiverse country. Although India constitutes only 2.4 per cent of the total land area of the world, it comprises 8 per cent to the known global biological diversity. In terms of Biogeography, India has been divided into 10 biogeographic zones.
