Answer: B

Explanation:

The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will be both water efficient and high performing. The WaterSense label is a voluntary program by the U.S. Environmental Protection Agency (EPA) that identifies and promotes water-efficient products that meet EPA’s specifications for water efficiency and performance. The label applies to tank-type toilets, water-using urinals, private lavatory faucets, and showerheads. For projects outside the U.S., local equivalents may be used if they meet the same criteria as WaterSense or are listed on the USGBC website. The label does not imply that the fixtures are LEED compliant, comply with mandatory federal government regulations, or comply with all international plumbing system requirements.
