Answer:
The correct answer is - Extinction.
Explanation:
When a conditioned stimulus is repeatedly presented without the unconditioned stimulus the extinction of the conditioned response will occur, In classical conditioning.
For example, in Pavlov's classic experiment, the salivation in dogs occurs when the sound of the bell occurs, but if the food is not presented with the sound of the bell. The salivation response eventually became extinct.
Thus, the correct answer is - Extinction.
