The correct answer is <u>C</u>: believe me / for mine honour.
Explanation:
In these lines from William Shakespeare's "Julius Caesar", Brutus invites the people of Rome to believe him for his honour and to respect him because of it. He uses ethos, a rhetorical model of persuasion, where the speaker appeals to the audience to listen to him or to trust him by emphasizing his credibility and authority.
By using ethos, Brutus wants to make his statement more authentic and credible and wants to convince people that he is telling the truth.
