A tendency toward violent behavior has been associated with each of the factors below except

A) low testosterone levels.
B) lack of guilt after hurting someone.
C) watching a lot of violence on television.
D) weaker than normal physiological response to arousal.

Low testosterone levels have actually been associated with decreased aggression, so they would not be a factor in a tendency toward violent behavior. The other factors listed (lack of guilt, exposure to violence, and weaker physiological response to arousal) have all been linked to an increased likelihood of violent behavior.
