Answer:
c. wtih physically differing populations which can still successfully reproduce
Explanation:
Polytype is when a single species has many variations in its area of coverage, it is thought that they are distinct species, or when many varieties or breeds of the same species are produced, as in the Lobos, which is naturally already polypic, and many dog breeds are still bred within the subspecies Canis lupus familiaris. In other words, we can say that in a polytyp species, many individuals have very different physical characteristics, but are of the same species, so they can reproduce successfully.
