When off loading garbage to another ship, your records must identify that ship by name and __________.

Correct Answer: Option D — official number

MARPOL Annex V and 33 CFR 151.55 require that when garbage is discharged to a reception facility or another vessel, the Garbage Record Book must be updated. This entry must include the date, time, location, and the official number of the receiving vessel to ensure full regulatory traceability.
