正解:B
* Risk Acceptance means acknowledging a risk and choosing not to take further action because the cost of mitigation may outweigh the benefits.
* It is the last resort when:
* The risk is low impact or unlikely to occur.
* Other options (mitigation, transfer, avoidance) are not feasible.
Why Not Other Options?
* A (Transfer) # Moving risk to a third party (e.g., insurance).
* C (Mitigation) # Implementing security controls to reduce risk.
* D (Avoidance) # Eliminating the risk entirely (e.g., discontinuing a service).
