Alcohol-resistant foam is used for polar solvents. Which option best completes this statement?

Explanation:
Alcohol-resistant foam is designed to fight fires involving polar solvents. Polar solvents, such as alcohols and some ketones, mix with water and can break down ordinary foams, preventing them from forming a stable blanket on the liquid. The alcohol-resistant formulation includes film-forming components that resist that breakdown, allowing the foam to spread over the surface, cool the fuel, and keep the fire suppressed. Because of this, the best completion is polar solvents. Nonpolar solvents are typically better tackled with standard hydrocarbon foams, while water-based or aromatic solvents don’t rely on the same AR performance.
