The correct answer is based on safety protocols established for handling flammable materials around aircraft fuel transfer locations. It is crucial to maintain a safe distance to prevent ignition sources from causing fires or explosions in the event of a fuel spill or vapor release.

In this context, the recommendation of not allowing smoking or flames within a distance of 3 feet acknowledges the need to minimize risk while also considering practical safety measures that can be easily enforced in operational environments around aircraft. Keeping a buffer zone of this size helps ensure that any potential fire hazards are significantly reduced, as the area directly adjacent to where fuel is being handled is particularly sensitive to ignition sources.

Establishing a smaller distance would not adequately address the risks associated with vapor dispersion and potential ignition sources, whereas a larger distance might be impractical in typical operational settings, where space may be limited. Therefore, the 3-foot guideline strikes a balance between safety and operational feasibility.
