AExcessive lube oil consumption.
BCorrosion of the journals and bearings.
CContamination of the lube oil.
DExcessive water discharge rate from the lube oil purifier.
AI Explanation

You are correct, the answer A) Excessive lube oil consumption is the correct answer. If there is a leak in the lube oil cooler while the vessel is underway, it would result in excessive lube oil consumption. This is because the leaking lube oil would be lost from the system, requiring the engine room crew to replenish the lube oil more frequently than normal. The other options, while potentially related to lube oil issues, do not specifically indicate a leak in the lube oil cooler.
