From the words lettered A to D, choose the word or group of words that best completes each of the following sentences.
The issue on....I disagreed with him is very simple

Answer Details

The correct option to complete the sentence is "which". "Which" is used to refer to a thing or idea, while "whom" is used to refer to a person, "what" is used to refer to a thing, idea or person when asking for information, and "whose" is used to indicate possession. Therefore, in the sentence "The issue on which I disagreed with him is very simple," "which" is used to introduce the clause that describes the issue in question.
