Under what conditions is it permissible to pump machinery space bilges directly overboard without processing by an oily-water separator?

AI Explanation
The correct answer is B) When presented with a flooding emergency. The reason this is the correct answer is that under the International Convention for the Prevention of Pollution from Ships (MARPOL), direct discharge of machinery space bilges overboard is only permitted in emergency situations, such as when there is a risk of flooding or capsizing. In a flooding emergency, the safety of the vessel and crew takes precedence over strict pollution prevention requirements. The other answer choices do not meet the criteria for legal overboard discharge under MARPOL.
