Answer: The sentence that uses the word "consult" correctly is A. He decided to consult his dictionary to find the true meaning.
Explanation: The word "consult" is a verb and it is used to refer to the action of seeking information or advice from a book or a person. Moreover, most times, "consult" is used as a transitive verb; therefore, it usually requires an object. The only sentence in which "consult" has been used correctly is the first one ("He decided to consult his dictionary to find the true meaning") since this verb collocates with the word "dictionary", which is functioning as its object. Moreover, unlike in the other sentences, the use of "consult" in the first sentence is coherent with the context.
