Answer: B. D) are not materially different from ethical principles in general.
Step-by-step explanation:
Ethical Principles are Ethical Principles. It doesn't really matter what context they are being applied to for they are a standard thing with reference of course, to the society the business is based in. For this reason Business Ethics are not materially different from general ethics.
Business Ethics are usually a reflection of the norms and cultures of the society they are based in. Think of it like this, if a company is based in a certain place and adheres to principles that are different from what is considered ethical in that society, do you think that company will be very profitable? I think not. Business Ethics are therefore based on General ethics with an immaterial difference.
