The stakeholders who are PRIMARILY responsible for determining enterprise IT risk appetite are the executive management and the board of directors, because they are the ones who set thestrategic direction and objectives of the enterprise, and who define the acceptable level of risk exposure and tolerance for achieving those objectives. The other options are not the primary stakeholders, because:

Option A: Audit and compliance management are responsible for providing assurance and oversight on the effectiveness of the risk management process and the compliance with internal and external requirements, but they do not determine the enterprise IT risk appetite.

Option B: The CIO and the CFO are responsible for managing the IT resources and the financial resources of the enterprise, respectively, but they do not determine the enterprise IT risk appetite.

Option C: Enterprise risk management and business process owners are responsible for identifying, assessing, and responding to the risks that affect their domains, but they do not determine the enterprise IT risk appetite. References = Risk and Information Systems Control Study Manual, 7th Edition, ISACA, 2020, p. 83.
