Doppler is charged with aggravated assault on Vezy, a game warden. Doppler testified that, when he was confronted by Vezy, who was armed and out of uniform, Doppler believed Vezy was a robber and shot in self-defense. The state calls Willy to testify that a year earlier, he had seen Doppler shoot a man without provocation and thereafter falsely claim self-defense. Willy's testimony is 
admissible, as evidence of Doppler's untruthfulness.  admissible, as evidence that Doppler did not act in self-defense on this occasion.  inadmissible, because it is improper character evidence.  inadmissible, because it is irrelevant to the defense Doppler raised.
