Which conspirator's manipulation and distrust in Caesar's rise spurs the plot?

• A. Brutus
• B. Cassius
• C. Antony
• D. Calpurnia

Answer: (B)

Cassius is the conspirator who drives the plot by doubting Caesar’s rise and actively shaping others to act on that distrust. He resents Caesar’s ascent to power and believes Rome would be endangered by a single ruler, so he decides to undermine Caesar from the inside. To pull Brutus into the plan, he uses flattery about Brutus’s virtue and makes it seem as if resisting Caesar is a common-sense defense of the Republic. He even fabricates letters to appear as popular sentiment backing Brutus’s action, presenting manipulation as a duty to Rome. That combination of distrust and calculated manipulation is what spurs the conspiracy forward, with Brutus ultimately joining because of Cassius’s influence. (Brutus is the one who acts on Cassius’s manipulation; Antony later rises as an ally of Caesar’s memory, and Calpurnia is Caesar’s wife and not part of the plot.)
