Solution

The correct option is B Reproductive isolation of two groups of organisms.
The biological species concept defines a species as members of populations, that actually or potentially interbreed in nature, not according to similarity of appearance.
Reproductive isolation means when two groups of animals live close enough to one another to interact, but are unable to interbreed with one another. If two creatures cannot reproduce to produce fertile offspring of both sexes, then they are in different species.
