Accepted Answer

Ernst Mayr's definition of a biological species is a population or group of populations that can interbreed and produce fertile offspring. This definition emphasizes reproductive isolation as the key factor in distinguishing between different species. The other answer choices are either too broad (A, E) or too narrow (D) to capture the full concept of a biological species.
