Directions: In the following question, a sentence has been divided into three parts labelled (A), (B) and (C). Select the part having an error. If there is no error, then mark (D) as your answer.

The student, together (A)/ with his mother and teacher (B)/ are going to the principal’s office. (C)/ No error (D)

This is the correct option as this part of the sentence has the error. This sentence has subject–verb disagreement between the singular subject (the student) and plural verb (are going). For the sentence to be correct, the verb should also be singular (is going). The sandwiched phrase will not, in any way, alter the grammatical relationship between the subject and the verb.
