Answer:
B. Brutus cares about all Romans.
E. Brutus does not know how Caesar will change.
(Photo for proof at the bottom.)
Step-by-step explanation:
Brutus's line, "I know no personal cause to spurn at him but for the general" means that Brutus does not mean any personal harm towards Caesar when he kills him, but he will do it for the general good of Rome, since he believes Caesar is dangerous. When Brutus says "How that might change his nature, there’s the question," he is questioning how Caesar might change, so that's basically stating answer E.
