Explanation:
Some aphids make black walnut trees their habitat in the forest and only prefer to mate with aphids who have the same habitat. This is an example of reproductive isolation since these aphids now have different mating preferences and hence are isolated from rest of the aphids. The isolation occurred on the basis of difference in habitats so it is also an example of habitat isolation. Since the mating is prevented all together it is also an example of prezygotic barrier i.e. formation of zygote is inhibited. However, it is not an example of allopatric speciation since the aphids are not separated geographically from each other. They are present in the same area but have different habitat preference. Hence, option C is correct answer.
