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 a vessel must be either 1 1/2 inches or 2 1/2 inches, as specified in regulations for US Coast Guard-inspected vessels. The 2 1/2 inch size is the standard larger size connection required, while the 1 1/2 inch size is the smaller option. The other answer choices of 1 inch, 3 inches, and 3 1/2 inches are not valid fire hydrant hose connection sizes per the relevant regulations.
