Which defect category is described as likely to result in hazardous or unsafe condition under normal use?

• A. Major
• B. Critical
• C. Minor
• D. Developed Rust

Answer: (B)

Defect categories map to how much risk they pose during normal use. The category that signals a potential hazardous or unsafe condition is the one described as critical. This level is reserved for defects whose presence could lead to injury or dangerous operation if the item is used as intended, so safety is the primary concern. Major defects affect performance or reliability but aren’t necessarily hazardous, and minor defects are cosmetic or have negligible impact. Developed Rust is a specific condition, not a rating of risk, so it doesn’t represent the hazard level by itself. So the category described as likely to result in a hazardous or unsafe condition under normal use is critical.
