Answer:
conditioned response.
Explanation:
Ivan Pavlov gave the Classical conditioning theory in which an unconditioned stimulus which is food, in this case, results in unconditioned response (saliva). It is a biological process, therefore, requires no learning or conditioning. But by experimenting on a dog he explained that the learning process can be instilled by replacing them with condition stimulus (buzzer) and conditioned response (saliva). Therefore the neutral or unconditioned stimulus when replaced with conditioned stimulus which results in learned or conditioned response.
