Reproductive isolation refers to a set of mechanisms that prevent different species or populations from interbreeding, thereby maintaining distinct species. The correct answer is:

**b** the inability of two populations to reproduce due to biological barriers.

Biological barriers can include differences in mating behaviors, reproductive organs, or timing of reproduction, among others. Geographical barriers can also contribute to reproductive isolation but are more specifically described as "geographical isolation."
