Which of the following best describes a public servant's duty?

A public servant’s duty is fundamentally rooted in the principles of law and ethics, which is captured in the correct choice. Public servants are tasked with fulfilling their responsibilities as defined by legal mandates and ethical standards. This means they must act in a manner that is consistent with established laws and the ethical expectations of their roles, ensuring accountability and integrity in the services they provide to the public.

This adherence to law and ethical standards also fosters trust between the public and government institutions, promoting transparency and justice. Such a framework is crucial for maintaining the rule of law and ensuring that public servants prioritize the welfare of the community they serve.

In contrast, the other choices do not accurately reflect the essence of a public servant's duty. Acting without laws undermines accountability, avoiding risks runs contrary to the nature of public service, and serving one's own interests directly contradicts the public trust that is essential for effective governance.
