Answer: B) free association
Step-by-step explanation:
Free association is used during therapy to identify what a person is thinking without conscious assessment, thereby removing all barriers to their thoughts and feelings. In this example, Carolyn's therapist can understand what Carolyn is thinking without any suggestions from the therapist or any censorship from Carolyn.
This technique was developed by Sigmund Freud in the 1890s as a method to replace hypnosis.
