According to the Institute of Internal Auditors (IIA), the internal audit activity can play several roles in risk management, but its involvement should be advisory and facilitative in nature. The most appropriate role from the given options for the internal audit activity in an organization's risk management process is championing the establishment of a risk management framework. This includes advocating for risk management throughout the organization and helping management establish and improve the risk management framework without taking on management responsibilities, such as setting risk appetite or maintaining sole responsibility for risk management.
