The size of fire hydrant hose connections must be either 1-1/2 inches or _______________.
AI Explanation
The correct answer is A) 2-1/2 inches.
The size of fire hydrant hose connections must be either 1-1/2 inches or 2-1/2 inches, as per the standards set by the National Fire Protection Association (NFPA). The 2-1/2 inch size is the most common standard for fire hydrant connections, as it provides a larger flow capacity compared to the 1-1/2 inch size. The other answer choices (B, C, and D) are incorrect as they do not match the established standards for fire hydrant hose connections.
