Explanation

Option A (Reproduce Asexually) is the correct answer. Bacteria cannot be classified as species by the Biological Species Concept because they reproduce asexually, meaning that they do not exchange genetic material through sexual reproduction. This makes it difficult to define a group of interbreeding populations that are reproductively isolated from other such groups.
