A likely trigger for an RBI reassessment would be after:

API 580 Section 14.3.3 clearly states:

“Once a mitigation strategy is implemented it is prudent to determine how effective the strategy was in reducing the risk to an acceptable level. This should be reflected in a reassessment of the risk and appropriate update in the documentation.”

Thus, option B is correct. Updating standards or team members is not a listed reassessment trigger, and sensitivity analysis alone is a supporting tool, not a trigger.
