An area is declared as Hot Spot when the region must fall in two of the criteria. That is, it must contain at least 1,500 species of vascular plants as endemic species and have lost at least 70% to 75% of its original habitat. A biodiversity hotspot is a biogeographic region with an unusual concentration of species, many of which are endemic. It is marked by a serious threat to its biodiversity by humans.
So, the correct answer is option A.
