Final answer:
The correct answer is (A) Reduced hybrid fertility.
Step-by-step explanation:
The correct answer is (A) Reduced hybrid fertility. Prezygotic barriers are mechanisms that prevent or hinder reproduction from taking place. There are several types of prezygotic barriers, such as habitat isolation, behavioral isolation, and temporal isolation, which prevent species from mating with each other. Reduced hybrid fertility, on the other hand, is a postzygotic barrier that occurs after the zygote is formed and results in sterile hybrid offspring.
