Explanation

Option A is correct because Deming's system - known as the PDCA cycle - stands for Plan, Do, Check, and Act, the exact four phases he originally described for continuous improvement. Options B and D replace "Check" with "Evaluate," which is a plausible-sounding but incorrect substitution; Deming specifically used "Check" (later revised to "Study" in his updated model, but never "Evaluate"). Options C and D both swap "Do" for "Perform," which changes the original terminology without basis. A reliable memory tip: think of "PDCA = Please Don't Change Anything" - the first letters lock in Plan, Do, Check, Act in order, reminding you that the original wording must stay intact.
