Answer:
A). I wrote an essay about the benefits of exercise.
Step-by-step explanation:
An active verb is described as the verbs that are directly associated with the action of the subject in the sentence or the 'doer or subject' is performing the particular action.
In the given question, option A i.e. 'I wrote an essay about the benefits of exercise' contains an active verb 'wrote' that is directly performed by the subject 'I' in the sentence. It answers the question 'who wrote' by offering 'I wrote' while the other options fail to do so as they are affected by the action but do not perform it. Therefore, Options B, C, and D are incorrect as they employ passive verbs as the subjects are imposed to go through the action instead of directly performing it. Thus, option A is the correct answer.
