When consider means “regard as,” as it does in this sentence, its object should be followed immediately by the phrase that identifies or describes that object. Thus, to be in A, as in B, and as being in C produce unidiomatic constructions in the context of the sentence. Also, although if and whether can be used interchangeably after some verbs, question if, which appears in A and B, is unidiomatic, and they in B is unnecessary. E also contains the unnecessary they, and it uses the ungrammatical construction consider... facilities are. Grammatically and idiomatically, sound D is the best choice.
