Question 152General Subjects - 1st Asst/Chief

The correct answer is D) oily bilge water inlet line. The illustration GS-0175 is likely depicting the components of a marine oil-water separator or similar pollution control equipment. The line labeled "E" would be identified as the oily bilge water inlet line, as this is the line that carries the oily bilge water from the vessel's bilge into the oil-water separator for processing. The other answer choices are incorrect because they do not accurately describe the function of the line labeled "E" in the context of the illustration. The clean water inlet line, waste oil outlet line, and processed water outlet line would have different designations within the system.
