The answer is indeed letter A. Antony calls the assassins "honourable men” but subtly turns the crowd against them.
Explanation:
At this point of Shakespeare's play "Julius Caesar", Caesar has been betrayed and killed by his men. Mark Antony, who was loyal to Caesar, now pretends to be loyal to Brutus and Cassius, Caesar's assassins, to save his own life. However, at the funeral, he wittily shows the crowd that Brutus and Cassius are not good men. Even though he calls them "honourable", he does so ironically. The Roman people loved Caesar and very well knew his qualities. By emphasizing the fact that Brutus is trying to find some flaw to blame on Caesar, Antony shows the crowd that Brutus is against Caesar and should not be trusted. He then makes it clear that it is not just Brutus since "so are they all, all honourable men". Antony smartly conveys the very opposite of what his words are saying.
