Answer: b. Brutus says that he has not offended anyone and that he killed Caesar for the good of Rome, just as the people may kill him someday. As Caesar’s body is delivered, Brutus also acknowledges that Antony is not guilty, but will benefit from Caesar’s death, just as everyone will
Step-by-step explanation:
Since our purpose here is to choose the best summary for the monologue, I believe the best option to be the second one.
Options a and c do convey part of the message, but not all of it, leaving out some important details. Option d, on the other hand, gives too many details. It's closer to a paraphrase than to a summary, even though the two techniques sometimes overlap. A summary, however, tries to shorten the number of words while giving the same information. Therefore, option b seems to be more suitable: from it, we learn how Brutus justifies killing Caesar and how he acknowledges Antony's innocence. However, it is done in a brief manner.
