Explanation:

You can identify an active voice in a sentence if it contains a subject that reflects the intention of the verb. An active voice will usually begin with a subject in a sentence. In a sentence, an active voice contains a subject, verb, and object.

To further enhance your understanding, I will be citing a few examples. These examples are; I passed my English exams, Mary Jane wrote the poem, the vehicle hit the train, etc.

Option B is the answer because the subject "Class" does the action described by the verb "finished".
