Bstop the fuel oil pumping operation

AI Explanation
The correct answer is B) stop the fuel oil pumping operation. When the overflow tank high-level alarm sounds, it indicates that the fuel oil tanks are being overfilled. The proper action is to immediately stop the fuel oil pumping operation to prevent an overflow and potential spill. Closing the overflow tank filling valve (A) or the static leg filling valve (D) may help, but stopping the pumping (B) is the critical first step to address the high-level situation. Reducing the pumping rate (C) may not be sufficient to prevent an overflow.
