A Bill knоwn аs the Endаngered Species Act designаtes prоtectiоn for the critical habitat of an endangered species. The bill defines a species as ..." any subspecies of fish or wildlife or plants, and any distinct population segment of any species or vertebrate fish or wildlife which interbreeds when mature." Here the term interbreed means to breed with other members of its species, subspecies, or distinct population segment." So which of the following species definitions/concepts would be defining species as closely to the way this law is defining it as possible?

None of the answers below is perfect, but one would be closest to this legal definition.
