Answer:
d) operant conditioning
Explanation:
Operant Conditioning is a concept developed by American psychologist Frederic Skinner, one of the creators of Behavioral Psychology. It argues that our behaviors are responses to the positive or negative stimuli we receive and lead to certain consequences. Thus we can conclude that little Jeffrey's scandalous and rude behavior whenever his mother refuses to give him candy is a response to his mother's attitude of delivering what he wants whenever this behavior happens.
