Official USCG Answer & Rule Citation
Correct Answer: Option C — E liquid
Bunker C, or heavy fuel oil, is classified as a Grade E combustible liquid under 46 CFR. Grade E liquids have a flash point of 150°F or higher. Because of this higher flash point, they are considered less volatile than lighter fuels but still require careful handling to prevent accidental ignition.
