AI Explanation
The correct answer is C) 16 and 36. The fire control plan symbol 16 represents a carbon dioxide (CO2) extinguishing system, and symbol 36 represents a dry chemical extinguishing system. These types of systems are best suited for extinguishing Class B fires, which involve flammable liquids and gases. The other answer choices are incorrect because: A) Symbol 47 represents a foam extinguishing system, which is not the best option for Class B fires. B) While 16 (CO2) is correct, 47 (foam) is not the best choice for Class B fires. D) Symbol 26 represents a water sprinkler system, which is not the most effective for Class B fires.
