At the amusement park, Keon's heart begins beating rapidly and his palms begin to sweat. He reasons that since he is next in line for the roller coaster, he must be feeling exhilarated.

a) two-factor theory of emotion.
b) predictions of self-verification theory.
c) theory of self-monitoring.
d) theory of the looking-glass self.

The two-factor theory of emotion--A

Explanation:

The two-factor theory of emotion, also called the Schachter-Singer theory, describes emotion to be dependent on  cognitive factors and physiological arousal.
