In a vehicle inspection, what does 'EXT' signify?

Answer: B — Extinguisher

In the context of a vehicle inspection, 'EXT' refers to 'Exterior.' This term is commonly used to indicate components or elements of the vehicle that are visible from the outside and are crucial for ensuring the vehicle’s overall safety and roadworthiness. The exterior inspection typically includes checks on various parts such as lights, mirrors, doors, windows, and tire condition. The other options—while related to vehicle inspections—do not reflect the common abbreviation 'EXT' as used in the industry. For example, the engine might be inspected as part of an overall vehicle assessment, but it is not abbreviated as 'EXT.' Similarly, while fire extinguishers are important safety equipment that might be checked during inspections, they are usually not abbreviated this way. Lastly, the term 'extended' would not apply in this context, as it relates more to the length or duration of something rather than the inspection status or aspect being referred to. The clarity of these terms helps ensure that inspections are comprehensive and that all necessary checks are correctly documented and attended to.
