The correct answer is C. I wrote an essay about the benefits of exercise
Step-by-step explanation:
An active verb is a verb that is part of the active voice in which the action of the sentence is clearly performed by the subject of the sentence, in opposition to passive voice and passive verb in which the verb acts over the subject, this means in passive voice the focus is the recipient (subject affected by the action) and the action itself, while the passive voice focuses on the subject that performs the action. Considering this, the sentence "I wrote an essay about the benefits of exercise" belongs to the active voice and the verb "wrote" is an active verb as the action is directly performed by the subject "I" and the focus is on the subject performing the action and not the action acting over the subject. Also, the grammar structure of beginning with the subject and the verb directly connected to it suggest this is part of the active voice. Thus, the sentence that contains an active verb is sentence C.
