ANSWER

The correct option is B.

Reproductive isolation refers to evolution mechanisms that make it impossible for member of different species from successfully mating or producing fertile offspring. There are two different types of barriers that can prevent different species from mating, these are prezygotic and postzygotic barriers.

Prezygotic barriers are those hindrances that prevent different species from producing offspring by preventing formation of zygote. An example of this barrier is difference in courtship behaviors. Post zygotic barriers  prevent offspring produced by different species from being fertile, that is, they are sterile.
