Which statement about potable hoses is true?

• A. They are always stainless steel
• B. They are non-sterile by design
• C. They are safe, non-toxic and free from contamination; sunlight can promote algae growth on PVC piping
• D. They are made of PVC with no additives

Answer: (C)

The key idea is that hoses used for drinking water must not contaminate the water. They should be safe for potable use, non-toxic, and free from contaminants that could leach in or alter taste or safety. The statement that best fits this is that potable hoses are safe, non-toxic and free from contamination, which directly reflects the fundamental requirement for any equipment in contact with drinking water. It also adds a practical note about materials: algae and other growth can occur when water is exposed to light, so sunlight can promote algae growth on PVC piping, which is a consideration for maintaining water quality in systems that use PVC. Stainless steel hoses aren’t the only option, so saying they are always stainless is not accurate. Being non-sterile by design isn’t a defining feature of potable hoses, since the priority is safety and cleanliness, not sterility. And PVC with no additives isn’t typical for potable hoses, since many materials contain stabilizers and other additives to meet safety and performance standards.
