Correct option is B
Option 1: Boreal forest, tropical rainforest, tropical deciduous forest, alluvial grassland- Incorrect
- Boreal forests (Taiga) are NOT found in the Indian subcontinent. These forests exist in Canada, Russia, and Northern Europe (cold, subarctic regions).
- Tropical rainforest, tropical deciduous forest, and alluvial grasslands are present in India, but boreal forests exclude this option.
Option 2: Temperate forest, alluvial grassland, dry thorn forest, subtropical montane forest- Correct
- Temperate forests → Found in the Himalayas (Uttarakhand, Himachal Pradesh, Arunachal Pradesh).
- Alluvial grasslands → Present in the Indo-Gangetic floodplains (Terai region, Kaziranga, Sundarbans).
- Dry thorn forests → Occur in Rajasthan, Gujarat, and parts of Karnataka.
- Subtropical montane forests → Found in Himalayan foothills and Western Ghats.
All listed habitats exist in the Indian subcontinent!
Option 3: Scrub forest, Chapparal vegetation, dry grasslands, riparian forest- Incorrect
- Scrub forests exist in semi-arid parts of India (e.g., Rajasthan, Deccan Plateau).
- Dry grasslands are present in Madhya Pradesh, Rajasthan, and Gujarat.
- Riparian forests exist along riverbanks (e.g., Ganges, Brahmaputra, and Western Ghats).
- Chaparral vegetation is NOT found in India!
- Chaparral is a Mediterranean ecosystem (California, Chile, South Africa, Australia).
- Its presence makes this option incorrect.
Option 4: Shola grasslands, alpine grasslands, tundra, warm broadleaved forest- Incorrect
- Shola grasslands → Found in Western Ghats (Tamil Nadu, Kerala, Karnataka).
- Alpine grasslands → Found in Himalayan regions (Uttarakhand, Sikkim, Ladakh).
- Warm broadleaved forests → Exist in Northeast India, Western Ghats, Andaman & Nicobar Islands.
- Tundra is NOT found in India!
- Tundra is a polar ecosystem found in Arctic, Antarctica, and high latitudes (Siberia, Alaska).
- Ladakh and other high-altitude cold deserts have alpine grasslands, NOT true tundra.
