本题详细解析:
An analogous structure is one that has a similar function to other structures but does not come from a common ancestor. Choice B is a forelimb, but does not have a structure similar to the other three limbs, which indicates that it does not come from a common ancestor, so is likely to be analogous. Choices A, C and D are incorrect as they are all homologous to each other i.e. they share a common ancestor, evidenced by the similarities in their structures.
