Correct Answer:
B) Drainage and other wastes from toilets, urinals, medical areas, and spaces containing living animals

Explanation:
According to MARPOL Annex IV, "sewage" includes drainage and other wastes from toilets, urinals, and medical areas, as well as waste from spaces containing living animals. It specifically refers to human waste and similar pollutants that must be treated or managed before discharge.

Correct Answer:
B) It can be discharged when the ship is en route and at least 3 nautical miles from land

Explanation:
Sewage treated by an approved sewage treatment plant can be discharged at least 3 nautical miles from land, provided the ship is underway. This ensures that the treated sewage is safe enough to be released while minimizing environmental impact.

Correct Answer:
C) Drainage from toilets and urinals

Explanation:
Sewage under MARPOL Annex IV includes drainage from toilets and urinals, which contains human waste. Grey water and kitchen waste are not classified as sewage under this specific regulation, although they are managed under other guidelines.

Correct Answer:
A) It can be discharged at least 4 nautical miles from the nearest land

Explanation:
Sewage that has been comminuted and disinfected can be discharged at least 4 nautical miles from the nearest land, as long as the ship is moving. This ensures that the treated sewage is safe enough to be released without causing environmental harm.

Correct Answer:
B) It can be discharged at least 12 nautical miles from the nearest land, provided the ship is en route

Explanation:
Untreated sewage can be discharged into the sea at least 12 nautical miles from land, provided the ship is underway. This minimizes environmental contamination near coastal areas and ensures sewage is diluted effectively in open waters.
