What is the main function of a code of conduct in a profession?

Correct answer: Guiding ethical behaviour

The governing concept is professional ethics. A code of conduct sets expected standards of honesty, fairness, competence, confidentiality, respect and responsibility for members of a profession. It helps them judge difficult situations, prevents conflicts of interest and provides a basis for accountability when conduct falls below accepted standards. Therefore option B is correct: the code guides ethical behaviour rather than guaranteeing a particular profit or preventing all decisions. Hiding profit is dishonest, stopping decisions is not the purpose of a code, and removing customers contradicts responsible service. In management, such guidance supports trust and professional reputation.
