A therapist's goal is to delve into the unconscious processes of his patients. He is most likely to consider himself a practitioner of:

A) client-centered therapy.
B) rational emotive therapy.
C) psychodynamic therapy.
D) existential therapy.

Psychodynamic therapy is a therapeutic approach that aims to explore the unconscious processes of a patient in order to understand and address deep-seated psychological issues. This approach is rooted in the theories of Sigmund Freud, who believed that unconscious conflicts and repressed emotions could lead to psychological distress. A therapist practicing psychodynamic therapy would thus prioritize delving into the patient's unconscious mind and exploring the roots of their psychological issues.
