Pollution Prevention Regulations (33 CFR Part 156), state that no person may transfer oil to or from a vessel unless __________.

Correct Answer: Option B — all parts of the transfer system have been properly lined up

33 CFR 156.120 prohibits oil transfers unless the entire system is properly lined up. This ensures that all valves, pumps, and piping are correctly configured to prevent accidental spills, over-pressurization of tanks, or flow into unintended compartments, maintaining the integrity of the vessel's pollution prevention and cargo handling systems.
