Explanation
नॉर्मन मायर्स (Norman Myers) द्वारा 1988 में जैव विविधता हॉटस्पॉट (Biodiversity Hotspots) की अवधारणा दी गई थी। किसी क्षेत्र को हॉटस्पॉट के रूप में मान्यता मिलने के लिए दो मुख्य शर्तें पूरी होनी होती हैं:
उच्च स्थानिकता: उस क्षेत्र में कम से कम 1,500 स्थानिक पौधों की प्रजातियाँ (जो दुनिया में कहीं और न पाई जाती हों) होनी चाहिए।
आवास का नुकसान: उस क्षेत्र ने अपने मूल या प्राकृतिक आवास का कम से कम 70% हिस्सा खो दिया हो, यानी वह गंभीर पर्यावरणीय खतरे के दायरे में हो।
अतः सही विकल्प
- (C) है।
