Answer: (C)

The symbol for a cold water line is specifically designed to denote the pipes that carry cold water within a plumbing system. This is crucial in plumbing schematics and blueprints, as it allows plumbers and installers to readily identify the lines that deliver cold water to various fixtures and points within a building. This identification is essential for proper installation, maintenance, and troubleshooting of plumbing systems.

Understanding the symbol distinctly helps avoid confusion with other types of lines. For example, a hot water line symbol would represent hot water delivery, while a sewer line is specifically related to waste removal. Similarly, drainage lines correspond to the removal of used water and waste. Each symbol serves a unique purpose and conveys important information for the proper functioning and safety of the plumbing infrastructure, making it vital for those in the pipefitting profession to recognize and interpret these symbols accurately.
