Answer:
The correct answer is C. He appeals to the crowd's feelings and emotions by asking if they are proud to be Romans.
Explanation:
In his speech, Brutus tries to reach the feelings of the crowd and that themselves question whether they are proud to be Romans.
Brutus tries to persuade the crowd for him not to be judged for rising against Caesar. So he tells the crowd that his reasons were honorable, and that he did it exclusively for all of them.
He questions the crowd by telling them that if anyone does not feel a Roman, and therefore feels a slave, then he can judge him. In this way he tries to prove his innocence.
The use of Pathos is effectively to persuade a certain public by presenting your own argument and evoke the feelings and emotions of an audience to achieve a goal.
