Answer: A) The practitioner incorporating the principles of therapeutic use of self.
Explanation: The therapeutic use of the self is the ability of the therapist to be aware of himself and the patient and take care of what he communicates. It is as important as the techniques and knowledge and often makes the difference between success and failure in a treatment. By intervening therapeutically using our "I", counselling appears as a valuable tool that helps the therapist work more effectively to achieve the ultimate goal with the lowest possible personal cost.
