Answer:
B) Regression
Step-by-step explanation:
The defense mechanism that causes a person to fall prey to their baser instincts is called regression. This means that the person acts like they would before their ego was formed.
Here, when I tell my coworkers to throw spitballs at our boss we are behaving in way to assert dominance over our boss through socially unacceptable means. Even though we know that it is socially unacceptable we are acting like we do not.
Hence, the question is referring to B) Regression.
