Step-by-step explanation:
The set of events described in the question is best explained by Schacter's cognitive theory of emotion.
According to Schacter's two-factor theory, emotions are composed of two factors: physiological arousal and cognitive appraisal. In this situation, the initial physiological arousal from the sympathetic nervous system prepares the body for fight or flight. However, once the cat is seen and the situation is appraised as non-threatening, the physiological arousal is reinterpreted and labeled as excitement or amusement, resulting in laughter instead of fear.
This theory emphasizes the role of cognitive labeling and interpretation in shaping emotional experiences.
So, the correct answer is option b.
