What BEST describes an event?

In ITIL, an event is defined as any change of state that has significance for the management of a service or other configuration item (CI). Events are typically detected by monitoring tools. They are categorized as informational, warning, or exception to determine the appropriate response. This definition is broad and encompasses any detectable occurrence relevant to service management, not just failures or negative impacts.

A. This is the definition of a service request, which is a specific type of user-initiated demand, not an event.

B. This describes a major incident or a disaster, which is a specific, high-impact type of event, not the general definition.

D. This is the definition of a change, which is the process of altering a CI, not just a change in its state.
