Final answer:
The correct answer is c. jealousy, which is a complex emotion on Plutchik's wheel, arising from a combination of love, anger, and fear.
Step-by-step explanation:
Psychologist Robert Plutchik devised a wheel of emotions to illustrate various emotional states and their relations to one another. On his wheel, primary emotions are positioned at the center, such as happiness, sadness, anger, fear, disgust, and surprise. These emotions can combine to form more complex, secondary emotions. For example, love mixed with elements of anger and fear can result in the feeling of jealousy, which often involves worries about losing someone's affection and the anger related to perceived threats from others.
This concept underscores the complexity of our emotional responses, and how multiple feelings can merge into a distinct emotional experience, such as jealousy, which can be triggered by situations where we feel love is threatened by external factors, leading to anger and fear simultaneously.
