A building is defined as which of the following?

• A. A place with walls and a roof
• B. A place with walls and no roof
• C. An outdoor market
• D. A vehicle

Answer: (A)

A building is a sheltered, enclosed space defined by walls and a roof. The walls create a boundary and privacy, while the roof covers and protects the interior from weather, forming a defined interior area. That combination—walls plus a roof—is what distinguishes a building from other structures or spaces.

A place with walls and no roof isn’t fully enclosed and lacks the complete shelter that defines a building, so it doesn’t fit the definition. An outdoor market is typically open-air, lacking a continuous roof over the entire space. A vehicle is a mobile structure, not a fixed shelter built as a space to occupy or store things.
