Which of the following is the best statement of the contradiction to which Euthyphro thinks his critics are committed, per the underlined bit?

a. If it is wrong to prosecute one’s father, what Zeus did to his father was bad and unjust. Zeus is the best and most just of gods. Ergo, if it is wrong to prosecute one’s father, Zeus is both best and most just and bad and unjust. This is a contradiction.
b. Euthyphro’s critics contradict themselves in what they claim about the gods andabout Euthyphro.
c. Holiness means prosecuting wrongdoers, even your own family members. Unholiness means not prosecuting. Ergo, prosecuting one’s father for wrongdoing is both holy and unholy. This is a contradiction.
d. Everyone is mad at Euthyphro for prosecuting his father for wrongdoing, but he is doing the right thing. This is a contradiction.
e. Euthyphro is citing a family relation–Zeus’s authority as father figure–to prove that one should ignore family relations. This is a contradiction.
