Answer :
Answer:
B. B. F. Skinner.
Explanation:
B. F. Skinner was an American psychologist and behaviorist, famously known for his theory of Operant Conditioning. According to this theory, people's learning is dependent upon reward and punishment for their behavior.
He, in his theory, proved that our actions are not the result of our consciousness but external stimuli. Meaning that people repeat those actions which bring positive outcomes or rewards; they will avoid repeating those actions which involve punishment or negative responses.
So, the correct answer is option B.
