Answer: B

Explanation:

Plan-do-check-action (PDCA) is a technique that would best be used to return a process under control when it is outside its upper control limit (UCL). PDCA is a four-step cycle of continuous improvement that involves planning a change, implementing the change, checking the results, and acting on the findings. PDCA can help identify and eliminate the root causes of variation, improve the process performance, and prevent the recurrence of problems. PDCA is also known as the Deming cycle or the Shewhart cycle.
