Answer:
C). Forward chaining.
Step-by-step explanation:
Stimulus control methods are described as the methods that are inclined towards shifting one stimulus to another by creating a discerning that would function to control a specific behavior that was previously associated(under control) to another selective stimulus.
As per the question, except option C 'forward chaining' all the given options exemplify 'transferring the stimulus control from shifting one stimulus to another' as it is associated to teaching of a specific task to mark end to a particular identified/recognized behavior. Thus, option C is the correct answer.
