Answer: Biodiversity hotspots are home to nearly 20% of the world's population. Option B is most accurate.

A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.
Biodiversity hotspots host their diverse ecosystems on just 2.3% of the planet's surface, however, the area defined as hotspots covers a much larger proportion of the land, so much that it hosts about twenty percent of the world's population.
