Why B is correct
46 CFR §183.530(a) requires that electrical equipment in spaces containing machinery powered by gasoline or other fuels with a flashpoint of 43.3 °C (110 °F) or lower be explosion-proof, ignition-protected, or part of an intrinsically safe system. Gasoline has a flashpoint well below that threshold.
