The correct answer is D. Free association; psychoanalysis
Step-by-step explanation:
Free association is a common technique used in therapy; in this, the therapist asks the patient to express thoughts or ideas freely or to say whatever comes to his/her mind by asking questions, showing the patient images or similar. This is part of psychoanalysis as it is suggested the words or ideas of the patient show his/her conflicts, desires, frustrations, etc. that are part of the unconscious and subconscious mind, and therefore with the expertise of the therapist, these issues can be identified and addressed.
Clay's therapist is using this psychoanalysis technique because the therapist asks him to say whatever comes to his mind and therefore the therapists want to identify the conflicts or desires of Clay by analyzing his unconscious and preconscious mind through Clay's answers.
