Which type of construction requirements must APA-rated plywood meet?

APA-rated plywood must meet specific construction requirements that focus on fire resistance and classification standards. The correct classification for this type of plywood is Class A and it must have a 1-hour fire-resistance rating. Class A indicates that the material has the highest level of fire resistance, making it suitable for use in applications where fire safety is a significant concern.

In the context of building codes and fire regulations, the need for a 1-hour fire-resistance rating showcases the material's capability to withstand the effects of fire for a sufficient period, providing valuable time for evacuation and reducing the risk of fire spread. This is especially important in structural applications, where maintaining integrity during a fire is crucial for safety.

The other classifications outlined in the incorrect options represent lower levels of fire resistance or different fire classifications that are not applicable to APA-rated plywood. Thus, the requirements for Class A and a 1-hour fire-resistance rating reflect the expected performance standards for this type of building material.
