  1. A.Biosphere Reserve
  2. B.Wildlife Sanctuary
  3. C.Botanical Garden✓
  4. D.Sacred Grove

Correct Answer

(C) Botanical Garden

Solution & Explanation

Answer: (C) Botanical Garden. Solution: In situ conservation protects organisms within their natural habitat (biosphere reserves, national parks, sanctuaries, sacred groves). A botanical garden takes plants out of their habitat into a special setting, making it an ex situ method, so it is the odd one out. Biosphere Reserve, Wildlife Sanctuary and Sacred Grove are all in situ. NCERT: NCERT Class XII Biology, Ch 13 Biodiversity and Conservation, p.225, lines 16-19: "Ex situ Conservation- In this approach, threatened animals and plants are taken out from their natural habitat and placed in special setting... Zoological parks, botanical gardens and wildlife safari parks serve this purpose."
