AI Explanation
The correct answer is D) 350 psi and 406°F. According to the Coast Guard regulations, copper pipe is permitted to be used for steam service subjected to a maximum pressure of 350 psi and a maximum temperature of 406°F. This is specified in the regulations to ensure the safe use of copper pipe under the appropriate pressure and temperature conditions. The other options are incorrect because B) 250 psi and 406°F is below the permitted maximum pressure, and C) 250 psi and 460°F exceeds the permitted maximum temperature.
