Class BC. Class BC extinguishers handle both Class B (flammable liquid) and Class C (energized electrical equipment) threats. These are typically used in areas that have a high threat from flammable liquids and electronics/machinery. Pound for pound, these units will generally fight a flammable liquid fire more effectively than a Class ABC extinguisher.
This is the only appropriate extinguisher to use in kitchen conundrums. Even though class "K" fires are a subset of class "B" fires, they must be treated with extra care and thus warrant a dedicated extinguisher type. The wet chemical extinguisher can discharge for up to forty seconds at a maximum effective range of ten to twenty feet.
