In accordance with international MARPOL Annex V regulations and federal regulations under 33CFR Subchapter O, the prohibition of the discharge of all garbage applies to a vessel operating within how many nautical miles of the nearest land?

Correct Answer: Option A — 3 nautical miles

MARPOL Annex V regulations mandate a total prohibition on the discharge of all garbage within 3 nautical miles of the nearest land. This stringent requirement protects sensitive coastal environments and near-shore waters from contamination by ship-generated waste, requiring vessels to store all garbage until they are further offshore or docked.
