If a manager gives false information to a customer only for profit which professional feature is violated?

Correct answer: Code of conduct

A professional manager must deal honestly with customers and follow the ethical standards of the occupation. Giving false information merely to earn more profit is not a harmless sales technique; it deliberately misleads the customer and damages trust. Therefore, the professional feature violated is the code of conduct, shown in option A. Special knowledge, formal education, and entry rules describe other features of a profession, but none directly identifies the ethical failure in this situation.

The code of conduct tells professionals how they should behave while performing their duties. It requires honesty, fairness, responsibility, and respect for those affected by decisions. A manager may seek profit, but profit cannot justify deception. Since the manager knowingly provides incorrect information for personal or organisational gain, the conduct clearly conflicts with professional ethics. Thus option A is the most appropriate answer.
