Answer:
The correct answer is "James-Lange Theory".
Step-by-step explanation:
The James-Lange theory states that in order to feel emotion, the body must first experience some physiological responses to an external factor. This theory proposes that it is possible to predict the emotion that someone is feeling according to the body reactions that is experiencing. This is the case for Sarah's reactions when she talks to her philosophy professor. Sarah concludes that she does not like her professor because her heart races and she clinches her fists when she talks to the professor.
