The correct answer is Aristophanes.
The most important reason why this is the correct answer is that the remaining three playwrights (Plautus, Terence, and Seneca) weren't Greek - all of them were Roman. Only Aristophanes was a Greek writer, so he is the correct answer. Additionally, Seneca is known for his tragedies, not comedies, whereas Terence and Plautus did write comedies, but they are not Greek.
