Which of the following is a source of impulses? A. social norms
B. peer pressure
C. emotions

I think C because I've seen people who act impulsively when they are angry, like they say something they regret.  Social norms would not be a source of impulse because those are normal things. Peer pressure could be one too, but that involves other people.
