Answer & Explanation
The correct answer is Option D: Secure all sources of fresh air to the tank.
For a fire in a fuel tank, the first critical step is to eliminate the oxygen supply by securing all openings, vents, and fresh air sources. This starves the fire, helping to contain it before applying extinguishing agents and mitigating the risk of rapid spread.
