An argument by analogy compares two things based on a shared property or characteristic. The similarity between A and B is not that A is a species of B (A and B may not be related at all), nor that they are two names for the same concept (they may have different names but share a common property). It is also not necessary for A and B to be identical in every respect (they may differ in many ways except for one shared property). The best choice is B, as it captures the idea that A and B share some property, which is what allows for a comparison by analogy. E could also be a possible choice, but is more limited in scope as it only requires most referents of A to be also referents of B, whereas B allows for a broader range of similarities to be used in an analogy.
