Step 1: In quality control, defects are classified into three severity levels: critical, major, and minor.
Step 2: A critical defect can cause safety hazards or complete failure. A major defect significantly reduces the function or usability of the item and is likely to cause field failure. A minor defect is a deviation from specification that does not materially reduce the item's usability for its intended purpose.
Step 3: Option (A) describes stopping the process function, which is a critical/major level issue, not minor. Options (C) and (D) describe when a defect can be fixed or prevented, which is about handling, not severity classification.
Step 4: Only option (B) matches the standard definition of a minor defect, since it does not significantly impact performance or usability.
Final Answer: Option (B).
