Carl Rogers emphasized that a positive self-concept is promoted bya. an external locus of control. b. unconditional positive regard. c. reciprocal determinism. d. free association.

The answer is unconditional positive regard.

Unconditional positive regard is a technique to obtain the patient's trust during the therapy session.

This technique advocated that all therapists should provide unconditional acceptance and support to the patients regardless of the wrong/weird actions that the patients did.

Showing such support would lower their defense and make them become much more likely to open themselves up to the therapists. This will make it easier for them to treat their disorder.
