Answer:
This is an example of differential association.
Step-by-step explanation:
Differential association theory was created to explain why people tend to commit crimes. The theory states that such behaviour is largely learned through various ways. For example, by interacting with others. It also says that a person becomes a criminal due to continuous criminal patterns which later become a habit which is hard to let go. Differential association theory best fits in the given scenario because Bob is learning deceptive sales practices from his boss.
