Passage: Convergence is a process in which different species of organisms develop into one or more similar physical features in order to adapt to the same environment. The similarity between ichthyosaurs and fish is an example of convergence. Ichthyosaurs are marine reptiles and do not belong to the same class as fish. In order to adapt to the marine environment, the physical characteristics of ichthyosaurs tend to be consistent with those of fish. The most striking thing is that ichthyosaurs have fins like fish.
Question: If the above statement is true, which of the following options is a reasonable corollary of the above statement?
A. A.Members of the same kind of creatures who live in the same environment must have exactly the same physical features.
B. B.A creature cannot be grouped just because it has similar physical features to its members.
C. C.The physical characteristics of one kind of organism are similar to those of other species, which is entirely the result of their adaptation to the living environment.
D. D.Members of the same kind of creatures must have one or more physical features that distinguish them from other kinds of organisms.
