One of the reasons that alcohol increases aggression is that
a. ? alcohol increases serotonin activity, which tends to promote aggression
b. ? factors that promote aggression (e. g., frustration, violent media, etc.) have a stronger effect on people who are intoxicated than on people who aren't
c. ? people who are intoxicated tend to seek out situations where aggression is likely to occur
d. ? alcohol increases dopamine activity, which tends to promote aggression
