From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.

_____ were classmates in the university.

Answer Details

The correct option is "His sister and I were classmates in the university." This is because "his sister and I" are the subjects of the sentence, and in English grammar, the subject pronouns come before the verb. Using "me" instead of "I" would make it incorrect since "me" is an object pronoun and cannot be used as the subject of the sentence.
