In accordance with international MARPOL Annex V regulations and federal regulations under 33CFR Subchapter O, the prohibition of the discharge of unground paper products, rags, glass, metal, bottles, and crockery applies to a vessel operating within how many nautical miles of the nearest land?

Correct Answer: Option B — 12 nautical miles

Under MARPOL Annex V, the discharge of unground paper, rags, glass, metal, and crockery is prohibited within 12 nautical miles of the nearest land. These materials do not degrade rapidly and can cause physical damage to the seabed or marine ecosystems if discharged too close to the coastline.
