The biological species concept relies on the ability of individuals to interbreed and produce viable offspring. Therefore, it cannot be applied to asexual organisms, which reproduce asexually and do not mate. It also cannot be applied to extinct species that exist only in the fossil record. Therefore, options A and D are correct. As for option B, if hybrids are only produced in captivity, it may be due to environmental factors rather than true reproductive isolation, so it is not a good way to determine if two groups belong to the same species. Option C is not a valid reason since species showing little morphological diversity can still interbreed and produce viable offspring.
