Which of the following is MOST important for the determination of I&T-related risk?

The fundamental purpose of managing I&T-related risk is to support the achievement of business objectives. Therefore, the significance of any I&T risk is determined by its potential business impact. A technical vulnerability or threat is only relevant in the context of how it could affect the business services, processes, and goals that the IT system supports. Prioritizing risk based on business impact ensures that resources are focused on protecting what is most valuable to the enterprise.

B. Likelihood is a critical component of risk assessment, but it is meaningless without understanding the business impact of the event occurring.
C. The impact on competitors is an external business consideration, not the primary driver for determining an enterprise's internal I&T risk level.
