The primary basis for prioritizing risk responses is the impact of the risk. The impact of the risk is the consequence or effect of the risk on the organization’s objectives or operations, such as financial loss, reputational damage, operational disruption, or legal liability. The impact of therisk is one of the key dimensions of risk analysis, along with the likelihood of the risk. The impact of the risk helps to determine the severity and priority of the risk, and to select the most appropriate and effective risk response. The impact of the risk also helps to evaluate the cost-benefit and trade-off of the risk response, and to measure the residual risk and the risk performance. The other options are not the primary basis for prioritizing risk responses, although they may be considered or influenced by the impact of the risk. The replacement cost of the business asset, the cost of risk mitigation controls, and the classification of the business asset are all factors that could affect the value or importance of the business asset, but they do not necessarily reflect the impact of the risk on the business asset or the organization. References = Risk and Information Systems Control Study Manual, Chapter 4, Section 4.3.1, page 4-25.
