The correct answer is A - hamartia. "Hubris" means pride. "Anagnorisis" means a discovery character makes about himself, usually. "Peripeteia" means a turning point, a reversal of circumstances. Thus, the only correct answer is "hamartia", which means a tragic flaw that brings the character to his downfall.
