Final answer:
Statements A (Three hotspots cover high biodiversity regions in India) and C (Ex situ conservation involves relocating species to special settings) are correct, but the exact number of biosphere reserves, national parks, and wildlife sanctuaries in statement B cannot be verified with the provided information.
Step-by-step explanation:
Examining the provided statements regarding the conservation of biodiversity in India:
- (A) Three of the hotspot — Western Ghats and Sri Lanka, Indoburma, and Himalaya cover our country's exceptionally high biodiversity region.
- (B) India now has 14 biosphere reserves, 90 national parks, and 448 wildlife sanctuaries.
- (C) Ex situ conservation — In this approach, threatened animals and plants are taken out from their natural habitat and placed in special settings.
Each of these statements pertains to different aspects of biodiversity protection and conservation strategies. Based on the principles of biodiversity hotspots developed by Norman Myers and the practices of conservation, statements A and C are generally correct. However, without up-to-date numbers on biosphere reserves, national parks, and wildlife sanctuaries in India, the accuracy of statement B cannot be confirmed here. Thus, the safest answer would be D, statements A and C are correct, assuming statement B is not up-to-date or verified.
