Final answer:
The risk rating of an asset is calculated using the formula: Risk = Impact × Threat Rating × Vulnerability Rating. With the given values, the risk rating is 0.48. Hence, the correct answer is option d. 0.48. Therefore, the correct option is D.
Step-by-step explanation:
To calculate the risk rating of an asset, you can use the formula:
Risk = Impact × Threat Rating × Vulnerability Rating
Given the impact of 10, a threat rating of .12, and a vulnerability rating of .40, we can calculate the risk rating as follows:
Risk = 10 × 0.12 × 0.40 = 0.48
Therefore, the correct answer to the question is d. 0.48.
