Which of these playwrights is considered one of the greatest Greek writers of comic drama? Plautus Terence Seneca Aristophanes

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.
