C. 37
D. 40

Answer 1

Hint: Biodiversity hotspot is a biogeographic region which has extremely huge biodiversity that is threatened by human habitation, climate change, habitat loss or loss of species. Biodiversity contains different species of animal, plants and all other organisms.

Complete answer:
In this question, we have asked about the no. of biodiversity hotspot. First we'll learn a little about biodiversity hotspots. As we already know that biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitations. Around the world, 34 areas are declared as biodiversity hotspots. They occupy 2.4% of earth's land but 44 percent of the world’s plants and 35 percent of land vertebrates live in these regions. The Andes Mountains Tropical Hotspot is the world's most diverse hotspot. About 18% of the plant species in the world live in this region. Most plants in these hotspots are endemic, endemic means they are only found in these hotspots. Till now 34 hotspots have been declared.

So, the correct option is B. 34.

Additional information: India has 4 biodiversity hotspots: The Himalayas, the Western Ghats, the Indo-Burma region and the Sundarland and it also includes the Nicobar group of Islands. These hotspots have lots of endemic species.

Note:
The data can vary because new hotspots are declared. According to new data the total no. of biological hotspots are 36 as two more hotspots are added. But according to old data 34 is the correct answer. If we have 36 in the options, then we'll mark 36.
