Official USCG Answer & Rule Citation

Correct Answer: Option B — 203°F to less than 212°F

Heavy marine diesel and residual fuels require high thermal conditioning, typically maintained just below the atmospheric boiling point of water between 203°F and 212°F, optimizing separation efficiency without generating disruptive steam pockets within the centrifuge bowl.
