Answer:
The correct answer is option C) It emphasizes the savagery of the assassins' actions toward Caesar.
Step-by-step explanation:
Aesthetically, the word slaughter causes a much more "crude" effect than the word murder.
Shakespeare uses this so that we as readers can perceive the brutality with which Caesar was killed.
Not only because he was stabbed several times, but also because one of the people who killed him was Brutus. In addition to the brutality of the stabs, his death was agreed by a plot, not by something that Caesar has done particularly.
Given this information, we can say that the correct option is option C.
