Which of the listed substances can be satisfactorily removed from diesel fuel by centrifuging?

ASludge
BGasoline
CFuel oil
DLube oil
AI Explanation

The correct answer is A) Sludge. Sludge, which consists of water, dirt, and other impurities, can be effectively removed from diesel fuel through the process of centrifuging. Centrifugation utilizes centrifugal force to separate substances of different densities, allowing the sludge to be separated from the fuel. The other options, gasoline (B), fuel oil (C), and lube oil (D), are not substances that can be satisfactorily removed from diesel fuel by centrifuging. Gasoline and fuel oil have similar densities to diesel fuel, making it difficult to separate them using centrifugation. Lube oil is a different type of fuel altogether and would not be present in diesel fuel.
