A  are geographically isolated from one another, look alike, but are not capable of successful interbreeding.

B  may share the same geographic area but are so phenotypically different that they never attempt to reproduce.

C  have their own unique phenotypes and are geographically isolated from one another, but if they do happen to encounter one another, they are still capable of interbreeding although their offspring are infertile.
