Explanation:

Hand sinks must have water that is safe enough to drink. This is a basic requirement for hand - washing facilities to ensure hygiene and safety. Cloth towels can harbor bacteria and are not a must - have (disposable paper towels are more common in many settings). A spray nozzle is not a mandatory component for a hand sink.

Answer:

B. Water that is safe enough to drink
