Final answer:
Agents in business have a duty of honesty and fairness towards all parties involved: client, customer, and principal. This ethical guideline ensures that all dealings are conducted with trust, transparency, and integrity.
Step-by-step explanation:
An agent's duty of honesty and fairness applies to d) All of the above, which includes the client, the customer, and the principal. In the realm of business and agency law, agents are bound by ethical guidelines that mandate impeccable conduct toward all parties involved in a transaction. This duty ensures that agents act in good faith, disclose all material information, and do not deceive or exploit any party for personal gain.
The concept of 'agency' is central to business transactions, and the agent's role is to bridge the interests of the principal (the party for whom the agent acts) with those of the third party or client. Trust built on transparency and integrity is necessary for the maintenance of a healthy business environment and for upholding the reputation of both the agent and the principal. Therefore, it is paramount that the standards of honesty and fairness are uniformly applied across all interactions.
