What safety procedures should be followed during vehicle refueling?

Answer: B — Turn off the engine, avoid ignition sources, and use proper fuel handling techniques

The correct answer emphasizes the importance of safety during the refueling process. Turning off the engine is crucial because an operating engine can create sparks or heat that may ignite fuel vapors. Additionally, avoiding ignition sources—such as flames, static electricity, or electrical equipment—reduces the risk of a fire or explosion. Utilizing proper fuel handling techniques, which may include using an approved fuel container and ensuring good ventilation, is essential to safely manage flammable substances. While it's critical to ensure passengers exit the vehicle to minimize their risk, the most comprehensive approach to safety during refueling is captured in the correct answer.
