正解:B
ARO - annualized rate of occurrence is a representation of the frequency of the event, measured in a standard year. In our case number of the defecive device per year. Annualized Loss Expectancy (ALE) is the expected monetary loss that can be expected for an asset due to a risk over a one year period. This question is asking about loss of devices in a year. Annual loss expectancy (ALE) is the loss (amount of money) due ARO. The question is about the number of the device, not about money.
