Which statement best describes Drapery Casement's inherent property?

• A. moderately durable
• B. moderate resiliency
• C. flame resistant by finish
• D. inherently flame retardant

Answer: (D)

The key idea here is understanding what “inherent” means for a fabric’s fire behavior. When a fabric is inherently flame retardant, that property is built into the fiber’s chemistry itself—so the material resists ignition and slows burning as a natural part of its composition. This kind of protection stays with the fabric through washing and wear because it’s part of the fiber, not a surface coating. In contrast, “flame resistant by finish” refers to a chemical coating or treatment applied to the surface. That finish can wear off, wash away, or degrade over time, reducing or eliminating the protection. The other options describe mechanical or general performance traits (like durability or resiliency) and don’t address the fire behavior built into the material itself, which is why they’re not the best descriptor for the fabric’s inherent property.
