The correct choice for vehicles transporting passengers is a fire extinguisher rated at 2-BC. This rating indicates the extinguisher's effectiveness in fighting fires involving flammable liquids and electrical equipment, which are the primary concerns in a passenger transport vehicle.

The "B" in the rating refers to flammable liquids such as gasoline, oil, and grease, while the "C" signifies that the extinguisher is safe to use on electrical fires. Since passenger vehicles may be exposed to both types of hazards, a 2-BC extinguisher provides a sufficient level of protection.

Additionally, regulations and safety standards often dictate the required fire extinguisher rating for various types of vehicles to ensure passenger safety. A higher-rated extinguisher, while it may provide greater fire suppression capabilities, is not necessary for the general risks associated with transporting passengers. Hence, the 2-BC rating balances efficacy and practicality for this specific application.
