Final answer:
The correct answer to the question is C. Fire resistant, which refers to Type X gypsum board that is specifically designed to be fire-resistant and comply with ASTM standards.
Step-by-step explanation:
The question '______ gypsum panel complies with ASTM requirements for Type X gypsum board.' is asking which type of gypsum panel meets the American Society for Testing and Materials (ASTM) standards for being classified as Type X. The correct choice here is: C. Fire resistant.
Type X gypsum board is a special type of gypsum board that has fire-resistant properties. It is made with glass fibers mixed into the gypsum to increase its fire resistance. This type of board is required in certain areas of construction, particularly where enhanced fire protection is necessary.
Options A, B, and D (Moisture resistant, Curved walls, and Dirt resistant) refer to other properties that gypsum boards may have, but these do not specifically relate to the ASTM requirements for Type X fire resistance.
