Anotify the shore pumping station to reduce the pumping rate as tanks near full capacity

Bclose the deck filling valve to reduce the pumping rate

Cfill the tank to the bottom of the expansion trunk

Dclose all tank vents to prevent overflow

AI Explanation

The correct answer is A) notify the shore pumping station to reduce the pumping rate as tanks near full capacity. This is the correct answer because reducing the pumping rate as the tanks near full capacity helps prevent oil spills when topping off fuel tanks. Reducing the pumping rate allows the operator to more carefully monitor the tank level and shut off the fuel in a controlled manner before the tank overfills. The other options are incorrect because: B) closing the deck filling valve would not reduce the pumping rate, C) filling to the bottom of the expansion trunk could still result in an overflow, and D) closing the tank vents would not prevent overflow and could create a dangerous pressure buildup.
