Correct:
A
Explanation
The correct answer is Option 1 (1 and 2 only). This is based on the foundational criteria and institutional recognition of biodiversity hotspots.
- Statement 1: While the concept was pioneered by Norman Myers, the IUCN, in collaboration with organizations like Conservation International, plays a primary role in identifying, monitoring, and validating these regions globally to prioritize conservation efforts.
- Statement 2: Hotspots are strictly defined by their vegetation (specifically vascular plants). To qualify, a region must contain at least 1,500 species of vascular plants as endemics (0.5% of the world’s total). Vegetation serves as the primary proxy for overall ecosystem health and diversity.
- Statement 3: This statement is incorrect. In India, the recognized hotspots are the Western Ghats (not Eastern) and the Eastern Himalayas (not Western), along with the Indo-Burma region and Sundaland.
Thus, since statements 1 and 2 are scientifically and institutionally accurate, Option 1 is the most appropriate choice.
