Which statement best describes the inherent fire resistance of concrete and masonry?

Explanation:
Concrete and masonry have inherent fire resistance because their basic, noncombustible composition and substantial mass resist heat and flame exposure without needing any added protection. This natural resistance comes from the material itself, not from coatings or retrofits. While coatings or upgrades can enhance fire performance, they are external enhancements rather than the material’s built-in property. So, the fire resistance of concrete and masonry is inherent.
