The correct answer is A. George Washington Carver painted pictures while at Simpson College.
Explanation:
In language, the active voice occurs as the agent or subject is followed by the action it performs; this differs from the passive voice because in the passive voice the object and verb are placed first.
Active voice can be seen in option A, because in this sentence the subject (George Washington Carver) is followed by the verb and object (painted pictures). Also, the verb is used in a simple form, while in other options the verb contains a past participle that is used in the passive voice for example in option B the verb is "is remembered".
