Carl Rogers asserts that an effective psychotherapist will:

A) actively confront and challenge his or her client's erroneous beliefs.
B) interpret important transference and resistance behaviors for his or her client.
C) provide unconditional positive regard toward his or her client.
D) seek to identify how negative reinforcement is promoting maladaptive behaviors, feelings, and/or thoughts for an individual.

Answer: C
Rationale: In Carl Rogers' client-centered therapy, the therapist must show "unconditional positive regard" through genuine, empathetic, and nonjudgmental attention. According to Rogers, this was a critical part of the therapeutic process.
