Correct Answer:
Brutus appears skeptical of Antony
Reasons why the other options are not correct:
Option B: Brutus does encourage the citizens to respect Caesars memory.
Textual evidence: "Do grace to Caesar's corpse, and grace his speech tending to Caesar's glories which Mark Antony (by our permission) is allowed to make."
Option C: Brutus does instruct all of the citizens to remain present for Antony's remarks.
Textual evidence: "Good countrymen, let me depart alone. And, for my sake, stay here with Antony."
Option D: The citizens do willingly listen to both Brutus and Antony.
In the play the citizens listen to both Antony and Brutus' speeches.
I hope this helped! Good luck :)
