Answer:
b. sublimation.
Explanation:
Sigmund Freud has given defense mechanisms, through which a person tends to deal with unwanted impulses. He has mentioned ten defense mechanisms, and sublimation is one of them.
Sublimation: In psychology, sublimation is defined as the process of converting or transforming various undesirable urges or impulses into something desirable or things that can be considered as having little or no bad consequences. In other words, a person changes socially undesirable behavior into desirable behavior that can have a positive impact on a person's health and life.
Examples of unacceptable or undesirable behavior can be anger, jealousy, sexual impulse, etc.
In the question above, Freud would probably describe Ben's burst of creative and productive activities as an example of sublimation.
