Which of the following is a service provided by plumbing systems?

• A. Gas line installation
• B. Floor tiling
• C. Water supply
• D. Electrical wiring

Answer: (C)

Plumbing systems are responsible for delivering fresh water to a building and removing wastewater. The service they provide here is the water supply, which includes the network of pipes, fixtures, and valves that bring cold and hot water to taps, showers, and appliances, often coordinated with a water heater for hot water. Gas line installation is not part of plumbing; it belongs to the gas utility or heating system. Floor tiling is finish work, not a system service. Electrical wiring belongs to the electrical system, not plumbing.
