b. motivated forgetting.
Step-by-step explanation:
Motivated forgetting: In psychology, the term motivated forgetting refers to the psychological behavior that leads an individual to forget the unwanted memories of his or her life either unconsciously or consciously.
These unwanted memories include painful, unpleasant, and can threaten an individual's self- image that he or she desires to maintain. It is often considered as a defense mechanism as it signifies the conscious and unconscious coping strategies.
