On small passenger vessels how many supply and exhaust ducts are required in each enclosed space containing gasoline powered machinery or gasoline fuel tanks?

AI Explanation
The correct answer is C) 2 of each. According to the regulations in 46 CFR 182.405, each enclosed space containing gasoline powered machinery or gasoline fuel tanks on small passenger vessels must have at least 2 supply ducts and 2 exhaust ducts. This ensures adequate ventilation and air circulation to prevent the buildup of flammable vapors in these confined spaces. The other answer choices are incorrect because they do not match the regulatory requirement of 2 supply and 2 exhaust ducts per enclosed space. Having fewer than 2 ducts would not provide sufficient ventilation, while having more than 2 ducts is not necessary based on the regulations.
