Factors that usually determine hotspots are

• A. The number of total species (species richness)
• B. The number of unique species
• C. The number of species at risk (threat of extinction)
• D. All of the above
• E. Only a and b

Answer 1

The correct option is D All of the above

Biodiversity hotspots are geographic areas that contain high levels of species diversity but are threatened with extinction due to human activities. Basically, factors such as the number of total species in the given region, number of unique species and the number of species which are at the risk of extinction, are considered to mark a region as a biodiversity hotspot.
