After a risk has been identified, the risk owner is in the best position to select the appropriate risk treatment option. The risk owner is the person or entity with the accountability and authority to manage a risk1. The risk owner is responsible for evaluating the risk, choosing the most suitable risk treatment option, implementing the risk treatment plan, and monitoring and reviewing the risk and its treatment2. The risk owner has the most knowledge and stake in the risk and its impact on the objectives and activities of the organization. The other options are not the best choices for selecting the risk treatment option, as they do not have the same level of accountability and authority as the risk owner. The risk practitioner is the person or entity with the knowledge and skills to perform the risk management activities1. The risk practitioner can assist the risk owner in identifying, analyzing, evaluating, and treating the risk, but the final decision and responsibility lies with the risk owner. The business process owner is the person or entity with the accountability and authority to manage a business process3. The business processowner may be affected by the risk or involved in the risk treatment, but the risk owner is the one who has the overall responsibility for the risk. The control owner is the person or entity with the accountability and authority to ensure that the controls are properly designed, implemented, and operated4. The control owner can provide input and feedback on the effectiveness and efficiency of the controls, but the risk owner is the one who decides which controls are needed and how they are applied. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 2, Section 2.1.3, Page 51.
