The correct Answer is:
To solve the question regarding the assertion and reason about biodiversity hotspots, we will analyze both statements step by step. ### Step 1: Analyze the Assertion The assertion states that "Biodiversity hotspots are the regions which possess high levels of species richness, high degree of endemism and no loss of habitats." - **Species Richness**: This part is true; biodiversity hotspots do indeed have high species richness. - **Endemism**: This is also true; hotspots have a high degree of endemism, meaning many species are unique to those regions. - **No Loss of Habitats**: This part is false. For a region to qualify as a biodiversity hotspot, it must have lost at least 70% of its original habitat. ### Step 2: Analyze the Reason The reason states that "The total number of biodiversity hotspots in the world is 32 with two of these hotspots found in India." - **Total Number of Hotspots**: This statement is incorrect. As of now, there are actually 34 recognized biodiversity hotspots worldwide. - **Hotspots in India**: The assertion that there are only two hotspots in India is also incorrect; there are more than two hotspots, including the Western Ghats, Eastern Himalayas, and Indo-Burma. ### Step 3: Conclusion Based on the analysis: - The assertion is partially true (true for species richness and endemism, but false for habitat loss). - The reason is false (both the number of hotspots and the number in India are incorrect). Thus, the correct answer is: **(c) If assertion is true but reason is false.**
