In fault correction steps, which sequence is correct?

• A. Sequence B
• B. Sequence C
• C. Sequence A
• D. Sequence D

Answer: (C)

Fault correction works best when you follow a confirm–localize–diagnose–fix–verify pattern. Start by confirming the fault and reproducing it so you know exactly what isn’t working. Then locate where the fault originates, narrowing the area to prevent unnecessary changes. Next, identify the root cause and choose an appropriate corrective action. Apply the fix, then verify by re-testing to ensure the fault is resolved and no new issues were introduced. This order minimizes wasted effort and reduces the chance of masking symptoms or causing new problems. The option that follows this sequence is the correct one; other sequences that skip verification, jump to repair without confirmation, or skip localization can leave the fault unresolved or create new issues.
