AI Explanation

The correct answer is C) When the discharge is necessary to for the purpose of securing the safety of a ship or saving life at sea. This is correct because under 33 CFR Subchapter O, the regulations on the prevention of pollution from ships, the only permissible discharge of oil or oily mixture to the sea is when it is necessary for the purpose of securing the safety of a ship or saving life at sea. The other answer choices do not align with the federal regulations, which strictly limit the discharge of oil or oily mixtures to prevent marine pollution.
