Which of the following BEST mitigates ethical risk?

Ethics committees are formal bodies specifically established to oversee and guide an organization's ethical conduct. They develop policies, provide advice on ethical dilemmas, investigate breaches, and promote a culture of integrity, making them the most comprehensive and proactive mitigation for ethical risk.

Contingency scenarios are plans for responding to specific adverse events, not directly for preventing ethical breaches or promoting ethical conduct.

Awareness of consequences for violations can deter unethical behavior but is reactive and does not proactively foster an ethical culture or provide a mechanism for guidance.

Routine changes in senior management, while potentially bringing new perspectives, do not inherently mitigate ethical risk and can sometimes disrupt ethical governance if not managed properly.
