            A.By whom they were supposedly named is a passive construction that is unnecessarily indirect and wordy,
            especially immediately following another passive construction; the singular its does not agree with the
            plural antecedent the Glass House Mountains. B.This version of the sentence loses the causal connection,
            failing to explain why James Cook gave the mountains their particular name. C.As the object of a preposition
            and not the subject of the clause, James Cook does not work as the noun that the verbal phrase beginning
            with naming can describe; the preposition since loses the important causal logic of the sentence. D.Correct.
            This concise sentence uses active- voice construction in the relative clause and maintains agreement between
            the pronoun their and its antecedent. E The pronoun it does not agree with the plural Mountains and the
            following pronoun their.
