The correct option is B Eastern Himalayas
The Eastern Himalayas hotspot of our country extends to the Northeastern part of India and Bhutan. The Eastern Himalayas is recognised as the ‘Cradle of Speciation’ due to their rich diversity of primitive flowering plants. 63 percent of the genera of Indian land mammals, more than 60 percent of Indian birds, two endemic genera of lizards, 35 endemic reptilian species including two turtle species, and 68 amphibian species of which 20 are endemic, are found in this region.
