To define professional standards of conduct for information security professionals is the correct option.

A professional code of ethics exists to articulate the values and behaviors expected of practitioners and to provide a common set of standards for decision making and professional conduct. It helps information security professionals evaluate ethical dilemmas, maintain public trust, and promote consistency across the field.

Google Cloud Identity and Access Management is incorrect because that entry names a specific cloud service for managing user identities and permissions and it has nothing to do with issuing a professional code of conduct.

To offer guidance on resolving conflicts of interest is incorrect because that choice is too narrow. A code of ethics may address conflicts of interest, but its purpose is broader and focuses on defining overall professional standards and responsibilities.

To enforce compliance with laws and regulations is incorrect because codes of ethics provide ethical guidance rather than legal enforcement. Laws and regulations are enforced by legal authorities and regulators while a professional code guides behavior and may be used by professional bodies when judging ethical breaches.
