A . Floor decking
B . Asbestos insulation
C . Exterior glazing
D . Plumbing fixtures

Answer: A

Explanation:

The reuse calculation for MR Credit Building Life-Cycle Impact Reduction includes the surface area of structural elements that are reused in place or salvaged and reinstalled, such as floor decking, columns, beams, and roof decking. Exterior glazing and plumbing fixtures are not considered structural elements and are not included in the reuse calculation. Asbestos insulation is a hazardous material that should be removed and disposed of properly, not reused.
