The purpose of plumbing in a salon or school is not for decoration and aesthetic appeal (A), as plumbing serves a functional purpose rather than a decorative one. Additionally, energy conservation (C) is not the main purpose of plumbing in these settings, as energy primarily pertains to electricity consumption rather than water flow. Similarly, water rationing (D) is not the main purpose of plumbing in these settings, as plumbing is meant to convey water, not restrict its usage. Overall, the main purpose of plumbing in a salon or school is to ensure the safe and efficient conduction of water and waste, as stated in option (B) - to carry adequate quantities of water, prevent contamination, properly convey sewage, and avoid being a source of contamination or nuisance.
