BThe discharge of comminuted and disinfected sewage is permitted.
CThe discharge of disinfected sewage is prohibited, but the discharge of comminuted sewage is permitted.
DThe discharge of any sewage, treated or untreated, is prohibited.
AI Explanation
The correct answer is D) The discharge of any sewage, treated or untreated, is prohibited. This is because under MARPOL Annex IV, the discharge of any sewage, whether comminuted, disinfected, or untreated, is prohibited within 3 nautical miles of the nearest land. The regulations state that sewage must be retained onboard or discharged at a sufficient distance from land to prevent pollution. Options A, B, and C are incorrect because they allow some form of sewage discharge within the 3 nautical mile limit, which is not permitted under the MARPOL regulations.
