The Biological Species Concept Defines a Species as a Group

The biological species concept defines a species as a group of potentially interbreeding organisms that are reproductively isolated from the members of other species. Under this concept, species are separated by reproductive isolating mechanisms, which may intervene before a zygote is formed (prezygotic reproductive isolating mechanisms) or after a zygote is formed (postzygotic reproductive isolating mechanisms) .
-Which statement is an example of postzygotic reproductive isolation?

A) Sperm of species A dies in the oviduct of species B before fertilization can take place.
B) Hybrid zygotes between species A and B are spontaneously aborted early in development.
C) The mating seasons of species A and B do not overlap.
D) Males of species A are not attracted to the pheromones produced by the females of species B.
