Question 983 Deck General

The correct answer is D) final topping off is occurring. This is the most critical time during bunkering because it is when the fuel tank is nearly full and the potential for overfilling and accidental oil spills is highest. During the final topping off process, the tank level is closely monitored, and extra care must be taken to avoid overfilling. The other options, such as the start of bunkering (A) or disconnecting hoses (C), do not pose the same level of risk for accidental oil pollution.
