The correct option is C Breeds of the same species cannot look different.
A species is defined as a group of organisms which can interbreed among themselves and have fertile offsprings. A Species is considered indigenous to a given region or ecosystem and its presence in that region is the result of only natural processes, with no human intervention. One species can have multiple breeds. Breeds are formed by selective breeding and possess desirable characters and different breeds of the same species can have different phenotypic characters. For example, different breeds of dogs look vastly different from each other yet they all belong to the same species.
