Answer:b. Extinction.
Explanation:
According to Cooper, Heron, & Heward (2007), " Extinction as a procedure occurs when reinforcement of a previously reinforced behavior is discontinued; as a result, the frequency of that behavior decreases in the future."
An extinction procedure is used in Applied Behavioral Analysis and it involves taking steps in deliberately intervening to make a target behavior to reduce the frequency in occurring or stop totally . It generally means that if the reinforcement that initially triggers a behavior is discontinued, it will reduce the occurrence of such behavior in the long run.
