Final answer:
State-regulating agencies can revoke or suspend licenses, publish notices of violations, demand restitution, and require professionals to complete ethics courses as disciplinary measures.
Step-by-step explanation:
State-regulating agencies have several actions at their disposal when it comes to disciplinary measures against design professionals who breach rules of conduct. The professional's license may indeed be revoked or suspended as a direct consequence of such violations. Additionally, a notice of violation could be published to inform the public and serve as a deterrent to others. Through restitution, the professional may be compelled to return any unjust benefits or make amends for losses incurred due to their violations. It is also possible that the offending professional might be ordered to complete a course in ethics to better understand the values and responsibilities foundational to their profession. Therefore, the correct answer is D) I, II, III, and IV, which covers all possible actions provided by the question based on the principles of professional conduct and accountability.
