Which of the following plumbing fixtures apply to the calculations in Water Efficiency Prerequisite, Indoor...

According to the LEED V5 : Building Design + Construction Guide, the Water Efficiency Prerequisite, Indoor Water Use Reduction requires the project to reduce the aggregate water consumption from plumbing fixtures and fittings by at least 20% from the baseline. The baseline water consumption is determined by the Energy Policy Act of 1992 and subsequent rulings by the Department of Energy, or a local equivalent for projects outside the U.S. The plumbing fixtures and fittings that apply to the calculations are toilets, urinals, lavatory faucets (both private and public), showerheads, and kitchen sink faucets 1 . Pre-rinse spray valves, dishwashers, and commercial kitchen filling operations faucets are not included in the calculations, as they are considered process water uses 1 . Therefore, the correct answer is C, urinals, public lavatory faucets, kitchen sink faucets.
