B, and A are incorrect. These all are less significant than identifying controls.

Explanation:
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 Incorrect Answers:
B: Fault tree analysis provides a systematic description of the combination of possible undesirable occurrences in a system. It does not measure the extent of uncertainty.
C: Cause-and-effect analysis involves the use of predictive or diagnostic analytical tool for exploring the root causes or factors that contribute to positive or negative effects or outcomes, and not the extent of uncertainty.
D: Scenario 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.
But it plays no role in determining the extent of uncertainty.
