Potassium Carbonate is a Wet chemical.

Explanation:
Wet chemical extinguishers are specialized for commercial kitchen oil and grease fires (Class K) and work by delivering a potassium-based agent that saponifies fats, creating a soapy layer, cooling, and smothering the fuel. Because these systems rely on a liquid, potassium-based chemical designed for cooking-oil fires, they are categorized as wet chemical. The emphasis is on the intended use and mechanism rather than a simple “dry” or “gas” label, which is why this option is the correct choice.
