The exposure factor (EF) is the metric that defines the anticipated percentage of an asset's value that could be lost if a given vulnerability were exploited. This metric is a critical component of a comprehensive risk assessment. While the other options might appear related to risk management, none of them specifically measure the potential percentage loss of an asset's value due to exploitation. An 'impact score' is typically a generalized rating rather than a precise percentage. A 'financial loss ratio' is not a standard term in risk management and does not accurately reflect the value loss of an asset due to a vulnerability. 'Annualized loss expectancy' is a calculation of expected loss over a year and incorporates both the exposure factor and the annual rate of occurrence, rather than just the loss associated with a single incident.
