Deindividuation refers to a diminished sense of individual identity that can occur when people are part of a group, which can lead to increased impulsive and deviant behavior. Self-awareness, or a focus on one's personal identity and values, can help counteract this effect and decrease deindividuation. Anonymity, group size, and arousal are all factors that can increase deindividuation. Therefore, the best choice is C, self-awareness.
