At a psychology conference, Dr. Albers presents a paper extolling the virtues of psychoanalytic psychotherapy. Dr. Zerbolio, who is in the audience, is a staunch critic of psychoanalytic psychotherapy. ALL BUT WHICH is a valid criticism that could be offered by Dr. Zerbolio?

a. "Isn't it possible that by encouraging complete understanding—by spending so much time analyzing past behavior—the therapist and client delay making meaningful changes in the present?"
b. "If I'm not mistaken, the research is unclear on whether behavior change necessarily follows insight.".
c. "Even if psychoanalytic psychotherapy is effective, it seems to me that it's simply too costly for more than a small percentage of individuals needing treatment.".
d. "Based on my understanding, the research suggests that over half of clients receiving psychoanalytic psychotherapy report unsatisfactory relationships with their therapists.".
