Explanation:

To determine what a hand sink must have, we analyze each option:

• Option a: Cloth towels can harbor bacteria and are not a requirement (disposable or air dryers are more common in food service/health settings).
• Option b: Hand sinks must provide potable (drink - safe) water for proper handwashing, as contaminated water would defeat the purpose of handwashing.
• Option c: A spray nozzle is not a standard requirement for a basic hand sink; regular faucets are sufficient.

Answer:

b. Water that is safe enough to drink
