Directions: The following sentence has been broken in three parts (A), (B) and (C). If there is any grammatical error in any of these parts, that is the answer. If there is no error, the answer is (D).

The students, accompanied (A)/ by the teachers and the principal, (B)/ was going to the picnic. (C)/ No error (D).

This is the correct option as this part of the sentence has the error. The sentence has the subject-verb disagreement between the plural subject (students) and the singular verb (was). The correct sentence should have a plural verb (were), instead of the singular verb (was). The accompanying phrase does not, in any way, alter the relationship between the subject and the verb but only provides extra information.
