Answer:
B.
Step-by-step explanation:
Interrupted behavior Chain is the procedure used to teach the children suffering from autism. It is considered an effective measure to teach such a person.
In this procedure, the steps are sabotaged that are well known to the children. Meaning that when a child becomes familiar with a process, an adult will eliminate one of the steps to analyze the behavior or response of the child. The child will either protest or request.
In the given case, the Therapist gives crayons to Paige to color the worksheet eliminating pink color, which is her favorite color. So, when Paige found that her favorite pink color is missing, she requests the Therapist to give her pink color. This shows that the Therapist has used the strategy of Interrupted Behavior Chain.
So, the correct answer is option B.
