Which concern does Calpurnia raise about Caesar going to the Senate?

• A. She warns that Caesar's life is in danger due to her ominous dream.
• B. She fears Caesar will be crowned king that day.
• C. She believes Caesar should stay home to avoid danger.
• D. She thinks the Senate will strip Caesar of power.

Answer: (A)

Imminent danger signaled by an ominous omen is what Calpurnia is emphasizing. In that moment she recounts a troubling dream that seems to predict harm to Caesar if he goes to the Senate, and she pleads with him to stay home to avoid that danger. This is why the best answer is that she warns Caesar's life is in danger due to her ominous dream. The other ideas miss the focus on the omen and the specific threat to his life, rather than a political outcome or a general precaution.
