Answer:
Schachter-Singer
Step-by-step explanation:
"Schachter-Singer theory of emotion" is also referred to as "two-factor theory of emotion" and was proposed by Stanley Schachter and Jerome E. Singer. This theory of emotion is defined as a theory in which two different factors are required by an individual to experience emotion. The first factor is the environmental stimuli that ought to elicit a "physiological response" and then emotions felt by a person are being produced as a consequence of the "cognitive labeling" related to the emotion.
The correct answer is the Schachter-Singer theory of emotion.
