Answer: B

On the basis of being familiar with laws, regulations and other behavioral norms, fund practitioners must consciously abide by these norms. Specifically, it includes the following requirements: (1) Fund practitioners should strictly abide by laws, regulations and other behavioral norms. When norms at different levels of effectiveness have provisions for the same behavior, they should choose to abide by the more stringent norms. (2) Fund practitioners should consciously abide by various codes of conduct stipulated in the "Self-Discipline Code". (3) Fund practitioners should actively cooperate with the supervision of fund regulatory agencies. (4) Fund practitioners with supervisory responsibilities must faithfully perform their supervisory duties, promptly discover and stop violations of laws and regulations, and prevent violations of laws and regulations from causing more serious consequences. (5) Ordinary fund practitioners, although they do not have supervisory responsibilities, should also supervise whether the behavior of others complies with the requirements of laws and regulations. Once violations of laws and regulations are discovered, they should be stopped in a timely manner and reported to the superior department or regulatory agency.
