Final answer:

To prevent backflow and protect potable water, an air-gap should be created between the faucet and the flood rim of the sink, ensuring contaminated water cannot siphon back into the clean water supply.

Explanation:

In order to prevent backflow and ensure the safety of a potable water supply, air-gaps are essential. An air-gap is created by ensuring there is a physical space between the outlet end of a faucet and the flood rim of a sink or container. The purpose of this air-gap is to prevent contaminated water from being siphoned back into the clean water system, which could happen if the faucet is submerged or connected directly to a source of contamination. Hence, the correct answer to the question would be to create an air-gap between the faucet and the flood rim of the sink.

Moreover, the inclusion of air-filled tubes near water faucets as depicted in some figures is another method to prevent backflow by providing an air buffer. In plumbing systems, maintaining this separation is crucial for protecting drinking water from contamination, and it's a standard health and safety requirement in many building codes.
