• D. LEED is a financial auditing standard for construction projects.

Answer: (C)

LEED is a green building certification program that guides and verifies a building’s design, construction, and operation to reduce environmental impact and improve occupant well-being. It evaluates multiple performance areas—energy efficiency, water use, materials and resources, indoor environmental quality, and sustainable site development—and assigns credits for strategies that meet or exceed sustainability goals. Projects earn levels like Certified, Silver, Gold, and Platinum based on total credits achieved. It’s not about fire safety ratings, zoning rules, or financial auditing; it specifically measures how a building performs as a sustainable, healthy place to live or work.
