Answer: (C)

Copper is commonly used for water supply lines in residential plumbing due to its numerous advantages. It has excellent corrosion resistance, which prolongs its lifespan and maintains water quality. Copper also has natural antimicrobial properties, which can help ensure the water supply remains safe from bacteria. Additionally, copper pipes can withstand high pressure and temperatures, making them suitable for both hot and cold water applications. The material also exhibits good thermal conductivity, which aids in the efficient transfer of hot water, and it is relatively easy to work with for plumbing professionals, as it can be easily soldered for strong joints. This combination of durability, safety, and ease of installation makes copper a preferred choice in many residential plumbing systems, especially for potable water supply lines.
