Final answer:
The 'necessary and sufficient conditions of therapy' according to Rogers's 1957 article did not include the interpretation of transference but emphasized unconditional acceptance of the client, empathic understanding, and therapist genuineness.
Step-by-step explanation:
The question relates to Carl Rogers's famous 1957 article where he described the "necessary and sufficient conditions of therapy." Out of the options listed, A. Interpretation of transference is the one condition that Rogers did not include as part of his therapeutic approach. Instead, Rogers's client-centered therapy emphasized B. Unconditional acceptance of the client, C. Empathic understanding of the client's experience, and D. Therapist genuineness. Rogers's approach is distinguished from psychoanalytic therapy, in which interpretation of transference is a key element, while Rogers believed in the inherent potential for good within all people and the capacity for individuals to deal with their own issues if provided with the right therapeutic conditions.
