Answer: aversive conditioning
Step-by-step explanation:
Aversive Conditioning refers to how an unpleasant thing or punishment is used as a way of discouraging an undesired behavior. The subject given the aversive stimuli is likely to not like it or be influenced by it negatively which will lead to the subject giving up the behavior.
For example Monica has an issue of craving chocolates in a non stoppable way which can be very unhealthy behavior that can affect her health greatly hence introducing chocolates along with an aversive stimulus will discourage her love for chocolate because now this bitter taste isn't what she desires from chocolate.
