Final answer:
Operant conditioning
Step-by-step explanation:
b) Operant conditioning
In operant conditioning, organisms learn to associate a behavior and its consequence. A pleasant consequence makes that behavior more likely to be repeated in the future. In the example given, snapping a rubber band on your wrist every time you get the urge to smoke acts as a punishment, which is a type of consequence, and this helps to decrease the behavior of smoking. Therefore, this example demonstrates operant conditioning.
