The answer is D: A tragic hero finds redemption by the end of the comedy.
A tragic hero refers to the protagonist of a tragedy, not a comedy. The main difference, at least as Aristotle analyzed it in his Poetics, is that a tragic hero usually faces forces that go beyond his strength and he must grow able to face the events depicted in the tragedy, perhaps finding some sort of solace at the end or, more likely, death. In a comedy, the protagonist, by various twists of fate, finds redemption for his flaws at the end, but not by his own means and strength, but rather by accident.
