The answer is C) Species are populations that interbreed and produce fertile offspring

Species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group and produce fertile offspring. That means that organisms from different species could not exchange genes. Even if they do in some cases, there are pre- and postzygotic mechanisms which prevent having them fertile offspring.
