Which statement best captures the core duties of engineers toward the public?

• A. Safety and welfare of the public are paramount
• B. Perform services only in areas of their competence
• C. Extend public knowledge and appreciation of engineering and its achievements
• D. All of the above

Answer: (D)

Engineers owe the public duties that cover protection of safety and welfare, acting only within proven competence, and helping the public understand engineering and its impact. The best choice is the one that includes all three, because each element addresses a distinct aspect of responsible professional conduct: safety and welfare as the overarching priority, competence to ensure reliable and safe work, and public education to foster informed trust and decision-making. Taken together, these form the complete set of responsibilities toward the public, so incorporating all three is the most accurate description.
