Answer: (C)

Black iron pipe is the commonly used type of pipe for gas supply lines in New York City due to its strength and durability. When dealing with gas, it is essential to have a piping material that can withstand high pressure and potential corrosion from the gas it carries. Black iron pipe, which is made of steel and coated with a black oxide finish, provides an excellent option since it is specifically designed for gas applications and can handle the necessary pressure ratings effectively. In many municipalities, including NYC, the use of black iron pipe is a code requirement for gas lines due to its ability to provide a reliable and safe conduit for natural gas distribution. Black iron’s excellent longevity and its resistance to impact make it a preferred choice among plumbing professionals for this purpose.
