Answer:
A. Casca firmly reverses his position about including Cicero, as if he hadn't been the one to suggest it in the first place
C. Casca thinks he is making important decisions when Brutus is really the one leading the way
Step-by-step explanation:
The ironic thing about discussing whether or not to include Cicero in the conspiracy is that Casca firmly reverses his position about including Cicero, as if he hadn't been the one to suggest it in the first place and Casca thinks he is making important decisions when Brutus is really the one leading the way.
An action becomes ironic when the eventual outcome is different from the intended outcome.
