The correct option is A 8.1%
Species diversity in India
India is known to cover only 2.4% of the total landmass of the world but its contribution to all the genetic resources of the world is estimated to be around 8.1%. This indicates that out of every 100 species found across the world, approximately 8 species are found in India alone, in spite of the fact that it covers a very small part of the world’s total land area. This is the reason India is considered to be one of the 12 mega diversity countries of the world.
The total number of identified animal species in India is estimated to be around 90000 and that of plant species is around 45000.
