Which term describes the sink used for personal hygiene purposes?

• A. Lavatory
• B. Automatic Water Supply
• C. Hydraulically Designed Piping
• D. Sprinkler Activation

Answer: (A)

In plumbing terminology, lavatory refers to the sink used for personal hygiene, such as handwashing or face washing, and is the standard term for bathroom sinks in building codes and NFPA-oriented contexts. This matches the description of a sink dedicated to personal hygiene, making it the best fit. The other terms describe broader system concepts rather than a fixture: automatic water supply relates to a fire protection system’s water source, hydraulically designed piping concerns how piping networks are sized and arranged, and sprinkler activation describes the operation of a sprinkler head during a fire.
