Step-by-step explanation:
Dr. Smith's approach, where she lets her clients feel they are good people no matter what they say or do, is an example of Person-centered therapy. This therapeutic technique was developed by Carl Rogers and emphasizes the importance of three features in a therapist: unconditional positive regard, genuineness, and empathy.
In person-centered therapy, the therapist accepts the client for who they are, creating a supportive and non-judgmental environment. This approach helps clients explore their thoughts and feelings freely, leading to personal growth and self-acceptance. So, the correct answer is option b.
