Answer: The correct answer is B) Classical Conditioning
Explanation: Classical Conditioning is learning through association.
If someone when flying in an airplane has experienced certain negative stimuli repeatedly then he/she would associate flying with negative responses.
For instance: Flying in an airplane (Neutral stimulus)
Is paired with: Unconditioned Stimulus (Eating spoiled food) which in turn elicits an unconditioned response (Puking, feeling ill).
Then, the neutral stimulus transforms into a Conditionated stimulus which elicits a conditionated response.
That's called Classical Conditioning.
