Which statement best reflects engineering ethics?

• A. Engineers use knowledge for the advancement of human welfare.
• B. Engineers always prioritize profits over safety.
• C. Engineers avoid honesty and impartiality.
• D. Engineers must be honest and impartial, promoting the engineering profession.

Answer: (D)

Engineering ethics centers on integrity in how engineers act and a duty to the public good. The statement that engineers must be honest and impartial, promoting the engineering profession, best reflects this. Honesty ensures that risks, limitations, and results are reported truthfully, so the public and stakeholders can trust the work. Impartiality means making decisions based on evidence and safety, free from personal gain or bias. Promoting the profession shows a commitment to maintaining standards, competence, and public confidence in engineering work.

The other ideas fall short because prioritizing profits over safety violates the fundamental obligation to protect public welfare, and avoiding honesty and impartiality directly contradicts professional conduct. While using knowledge to improve human welfare is important, ethics require explicit honesty, impartiality, and responsibility within the profession.
