Option (D) is correct.
Biodiversity hot-spots specifically refer to 25 biologically rich areas around the world that have lost at least of their original habitat. They are characterised by large number of flora and fauna, abundance of endemic species and also large number of alien or exotic species. They are mostly found in tropical and temperate regions. There are no biodiversity hot-spots in polar regions.
