Answer:
c. exposure therapy
Explanation:
In psychotherapy, exposure therapy is a technique to treat anxiety disorders. It consists in exposing the patient to the anxiety source or its context without the intention to cause any danger to the patient. By subsequent exposures to this sources of anxiety, the anxiety is slowly removed.
In this example, Rebecca is afraid of water, so her therapist gets her to swim in the family's backyard pool three times a day for two consecutive weeks. We can see that Rebecca is being exposed to water but in a safe way (the family pool) and she will be swimming there for 2 weeks, therefore she is being exposed to the water in a safe environment on a regular basis. Therefore, this approach best illustrates exposure therapy.
