A1 inch
B2 1/2 inches
C3 inches
D3 1/2 inches
AI Explanation
The correct answer is B) 2 1/2 inches. The size of the fire hydrant hose connections on vessels must be either 1 1/2 inches or 2 1/2 inches, per the regulations in 46 CFR 34.10-10. This regulation specifies that the fire hydrant outlets must be 2 1/2 inches in diameter, unless the vessel has a self-propelled water pump of less than 350 gallons per minute capacity, in which case the outlets may be 1 1/2 inches. The other answer choices of 1 inch, 3 inches, and 3 1/2 inches do not match the required sizes specified in the regulations.
