A hybrid zone is properly defined as:

A) an area where the ranges of two closely related species overlap but do not interbreed.

B) an area where mating occurs between members of two closely related species, producing viable offspring.

C) a zone where members of two closely related species are kept separate by prezygotic barriers.

D) an area where members of two closely related species intermingle, but gene flow is prevented by mechanical isolation.
