What is the maximum oil content allowed for overboard discharge?

Explanation:
The limit being tested is the oil content in overboard discharges from oily water separator-treated bilge water. The international standard requires that the discharged water contain no more than 15 parts per million of oil. This 15 ppm ceiling is set to minimize environmental impact, since even tiny amounts of oil can harm marine life and create surface slicks. The other numeric options exceed or do not meet this MARPOL limit, so they aren’t the correct maximum.
