A vessel where potable water is stored.

A vessel where potable water is stored.

• A. Tank
• B. Cistern
• C. Reservoir
• D. Jug

Answer: (B)

Potable water is safe-to-drink water, and a cistern is a large container specifically used to store such water for use in buildings or on property. It is designed to hold water for distributing to taps or rainwater systems, keeping it ready for use while protecting it from contamination. A tank is a general container and could describe many different vessels, but the common pairing of “vessel for storing drinking water” is a cistern because of its traditional role in domestic water storage. A reservoir refers to a large body of water, not a container you store water in, and a jug is simply a small hand-held vessel, not suitable for storing water on a building scale. Hence, the best fit is cistern.
