The correct answer is D. implementing corrective action on items that have high risk priority number or severity values . The CSSBB source explains that after assigning probability (P) , severity (S) , and detection (D) , the risk priority number (RPN) is calculated as RPN = P × S × D . It further states that actions are then based on items that either have the highest RPN or have major safety issues .

This means the team should not rely on an arbitrary cutoff like RPN > 100. The source also emphasizes severity separately, especially for safety-related consequences and nonconformance risk. Therefore, the practical FMEA focus is to take action on the items with the highest combined risk and on any items with very high severity, even if the total RPN is not the absolute highest. The other choices are incorrect because alpha risk is unrelated to FMEA, and creating flowcharts is not the main prioritization rule. Thus, the verified CSSBB answer is D .
