According to the CRISC Review Manual, the risk owner is the person who has the authority and accountability to manage a specific risk and its associated controls1. The risk owner is also responsible for ensuring that the risk is within the acceptable level and that the risk response is effective and efficient2. Therefore, the most appropriate owner for a newly identified IT risk is the individual who has the authority to commit organizational resources to mitigate the risk, asthey have the most interest and influence on the risk and its impact on the business objectives. The other options are not the most appropriate owners for a newly identified IT risk, as they may not have the authority or the accountability to manage the risk. The manager responsible for IT operations that will support the risk mitigation efforts may have the operational responsibility or the oversight of the risk management activities, but they may not have the authority to allocate the resources or approve the risk response. A project manager capable of prioritizing the risk remediation efforts may have the project management skills or the knowledge of the risk management process, but they may not have the accountability or the ownership of the risk or its outcomes. The individual with the most IT risk-related subject matter knowledge may have the technical expertise or the understanding of the risk and its causes, but they may not have the decision-making power or the responsibility to manage the risk or its controls. References = CRISC Review Manual, pages 32-331; CRISC Review Questions, Answers & Explanations Manual, page 822
