Answer:
A). Brutus plans to kill Caesar.
C). Brutus will be part of the plot against Caesar.
D). Killing Caesar will prevent him from becoming a tyrant.
Step-by-step explanation:
A soliloquy is elucidated as the literary devices that the authors employ to disclose a character's underlying thoughts, intentions, and feelings while conversing with himself/herself.
In the given soliloquy from Act II, scene I of Shakespeare's popular drama i.e. 'Julius Caesar', Brutus reveals his inner thoughts and plans to the audience.
His plan of killing Caesar is reflected through his statements 'we put a sting in him', 'kill him in the shell.' However, the plan was initially framed by Cassius but Brutus becoming a part of his plan eventually which is mirrored at the very beginning of this soliloquy('It must be by his death') despite having 'no personal cause.'
The use of the pronoun 'we' substantiates the claim that Brutus joins the murder plot with Cassius against Caesar. His agreement to 'I grant we put a sting in him' clearly reflects that he participates in the plot.
The key reason for which Brutus joins the plan is 'to prevent Caesar from becoming a tyrant' as he clearly reveals that he does it 'for the general cause.' He feels that Caesar becoming the king might prove as dangerous as a 'poisonous snake.' Thus, options A, C, and D are the correct answers.
