The correct answer is D. Annualized Rate of Occurrence (ARO). ARO (Annualized Rate of Occurrence) represents how many times per year a specific threat or risk event is expected to occur. It is a key component in the ALE (Annualized Loss Expectancy) formula: ALE = SLE × ARO. For example, if a server is expected to fail twice per year, the AR

Explanation
ARO (Annualized Rate of Occurrence) represents how many times per year a specific threat or risk event is expected to occur. It is a key component in the ALE (Annualized Loss Expectancy) formula: ALE = SLE × ARO. For example, if a server is expected to fail twice per year, the ARO is 2. The other options are related but distinct: SLE is the monetary loss from a single incident, EF is the percentage of asset value lost per incident, and a Safeguard is a countermeasure to reduce risk.
