The following sentence contains a pronoun with an ambiguous antecedent. Choose the best revision to clarify the ambiguity.
"When John and his friend arrived, he was greeted by the host."
The best revision is
Correct: A
The original sentence contains an ambiguous pronoun "he," which could refer to either John or his friend. The best revision is choice A, which clearly states that John was greeted by the host. This revision eliminates the ambiguity and makes it clear who was greeted. Choice B is incorrect, as it changes the meaning of the sentence and implies that both John and his friend were greeted. Choice C is incorrect, as it still contains the ambiguous pronoun "he." Choice D is incorrect, as it also contains the ambiguous pronoun "he" and changes the subject of the sentence.
