Bfor centrifuging

Din a storage tank
AI Explanation

The correct answer is D) in a storage tank. The flash point of a residual fuel oil is used to determine the highest temperature to which the oil may be heated in a storage tank. This is because the flash point is the lowest temperature at which the oil can form an ignitable mixture with air. Heating the oil above its flash point in a storage tank could create a fire or explosion hazard. The other options (recirculating line, centrifuging, atomizing) do not directly relate to the use of the flash point as a safety limit for storage tank temperatures.
