What happens if a bilge pump fails to operate correctly?

The correct option highlights a critical concern regarding safety in marine operations. If a bilge pump fails to operate correctly, it can lead to water accumulation in the bilge, which is the lowest compartment of a ship where water tends to collect. This accumulation can pose a significant risk, as excessive water onboard may lead to a loss of buoyancy and stability, potentially causing the vessel to sink.

Overall, the bilge pump plays a vital role in managing water ingress, whether from leaks, wave action, or other sources. Therefore, its proper function is essential for maintaining the vessel’s safety and integrity at sea.
