Answer:
a. psychoanalytic
Step-by-step explanation:
In psychology, the psychoanalytic perspective is one of the mains schools of psychotherapy. It was founded by Sigmund Freud, and one of its main concepts refers to the existence of the unconscious.
According to him, we are motivated by unconscious needs and desires (which we are not aware of) and that have their roots in our early childhood experience. This perspective stresses the importance of early childhood experiences and their influence in our adult day-to-day lives.
In this example, Diana wants to find a therapist who will help her explore her unconscious motivations and how her early childhood experiences are affecting her now. We can see that the unconscious motivations and the importance of early childhood experiences are two of the main concepts in psychoanalytic perspective and therefore she should look for a therapist with a psychoanalytic perspective.
