Which is an example of classical conditioning? Multiple choice question.

B)

C)
A dog does not salivate when a bell is rung.

D)
A dog salivates when a bell is rung if food is present or not.

D.
Classical conditioning consists of a learned behavior over time. In this question the bell is stimulating the dogs wanting for food which cues the brain to salivate. Over time, the dog will correlate the bell being rung with food to being time to eat and will start to drool over it whether or not the food is present.
