A tragic hero is "a person who must evoke a sense of pity or fear in the audience." The hero has to confront his downfall, wheter its due to fate, his own mistake, or another reason.
Using this definition, the best example of a tragic hero is the powerful king that dies alone after his pride and vanity cause everyone to abandon him (C). His own mistake, his pride and vanity, led the hero to his downfall.
