The correct answer is the psychodynamic approach.
The psychodynamic approach is an insight-centered therapy approach, where the therapist's main role is uncovering the unconscious processes, thoughts, beliefs etc., that are influencing a client's behaviors and difficulties. By doing so, the therapist helps the client become self-aware of his or her behavioral patterns and unconscious intentions. Since Jin's therapist is helping her recognize her unconscious feelings of inadequacy, she is adopting the psychodynamic approach in therapy.
