Milo was charged with murder as a result of a fight that erupted with Victor while the two were watching a roller derby match. The defense called Winton, who test- ified that he saw the fight and that according to what he saw, Victor was the aggressor. Winton also testified that he had worked with Milo for several years and in his opinion Milo was a peaceful man. The prosecution then called Victor Jr. to the stand, who proposed to testify that his father was a peaceful, non-violent person. The defense objects, and Junior's testimony should be: (A) Inadmissible, because Milo has not specifically questioned Victor's character. (B) Inadmissible, because Victor's character may not be established by the testimony of his son. (C) Admissible, to rebut Winton's testimony that Milo was a peaceful man. (D) Admissible, to rebut Milo's claim of self-defense
