Referring to the illustration, note that the solenoid in line "C" is closed. The check valve in line "E" is open. The separator service pump is running. The check valve in line "G" is closed. Valve "B" is open. Valve "D" is closed. What is the operational status of the oily-water separator unit? Illustration GS-0175

AI Explanation
The correct answer is D) The oily-water separator is in the bilge water separation processing mode with water discharging overboard with an oil content less than 15 ppm.
With the solenoid in line "C" closed, the check valve in line "E" open, and the separator service pump running, the oily-water separator is actively processing bilge water. Since the check valve in line "G" is closed and valve "D" is closed, the processed water is being discharged overboard, not back to the bilge water holding tank. With these conditions, the oil content of the discharged water must be less than 15 ppm to comply with international regulations for overboard discharge.
The other options are incorrect because they either indicate the oil content is greater than 15 ppm or the water is being discharged back to the bilge water holding tank, which is not the case based on the given information.
