What is the downfall of the hero in a tragedy?
a) the actions of the villain
b) his own actions
c) a weak point in his character

I'd say its C because the actions of the villian does not have anything to do with the hero himself. A;so. his own actions should not be a downfall or else he wouldn't be a hero. - I'd say C.
