Identifying which of the following would BEST help an organization define an IT asset's criticality?

Comprehensive and Detailed Explanation (aligned to ISACA CRISC guidance)

CRISC suggests that asset criticality is determined by the business processes and services the asset enables, and the impact if those processes are disrupted. By mapping IT assets to business processes, the organization can understand which systems support revenue generation, regulatory compliance, safety, or other critical outcomes. The data classification policy helps assess data sensitivity (confidentiality), which is related but not sufficient by itself to determine overall criticality; availability and integrity requirements also matter. The number of business users may indicate importance, but some highly critical systems (e.g., settlement engines, control systems) may have few users yet enormous impact. End-of-life status is relevant for obsolescence risk but does not necessarily correlate with business criticality. Therefore, linking assets to the processes they support is the most reliable basis for defining criticality.
