Class A extinguisher ratings: 4A rating corresponds to how much water equivalence?

Explanation:
Class A ratings express how much water-like extinguishing power an extinguisher has for ordinary combustibles. The numeric part reflects a water-equivalent amount from a standard test. A rating of four A corresponds to roughly twenty liters of water-equivalent capacity, which is why twenty liters is the correct choice. The other volumes would align with different A ratings, not with the four A rating.
