Which of the following is a main component of a building?

• A. Roofing system
• B. Electrical system
• C. Foundation system
• D. Landscaping

Answer: (C)

Key idea: identify what parts are considered part of the building itself versus external site work. The foundation system is the base that supports the entire structure, transfers loads to the ground, and resists movement and settlement. Without a solid foundation, the rest of the building has nothing to stand on, so it is a fundamental component. The roofing system is essential for protection and sits on top of the structure, while landscaping is external site work, not part of the building. Therefore, the foundation system is the main component.
