Suggested Answer: C 🗳️
Fault tree analysis (FIA) is a technique that provides a systematic description of the combination of possible occurrences in a system, which can result in an undesirable outcome. It combines hardware failures and human failures.
Incorrect Answers:
A: Sensitivity analysis is the quantitative risk analysis technique that:
Assist in determination of risk factors that have the most potential impact Examines the extent to which the uncertainty of each element affects the object under consideration when all other uncertain elements are held at their baseline values
B: This analysis provides ability to see a range of values across several scenarios to identify risk in specific situation. It provides ability to identify those inputs which will provide the greatest level of uncertainty.
