Which statement best reflects key considerations when selecting impact-resistant gypsum board?

• A. Finishes compatibility, board thickness for rigidity, moisture resistance variants, and applicable code requirements are considerations.
• B. Type X is the only factor considered.
• C. Finishes compatibility is irrelevant.
• D. Color of the board determines suitability.

Answer: (C)

Selecting impact-resistant gypsum board involves balancing several real-world factors, not just one property. Finishes compatibility matters because the surface finish (paint, wallpaper, coatings) must adhere properly to the board and not compromise performance or durability. Board thickness for rigidity matters because thicker boards provide greater stiffness and better resistance to denting or impact. Moisture resistance variants are important in environments with humidity or moisture exposure, as choosing the right variant helps prevent deterioration and mold. Finally, code requirements guide the minimum fire ratings, thickness, labeling, and installation details needed for safety and compliance.

So the best statement is the one that includes finishes compatibility, board thickness for rigidity, moisture resistance variants, and applicable code requirements. The other choices are too narrow or ignore important factors (finishes compatibility is not irrelevant; Type X is not the only factor; color does not determine suitability).
