a.The structural strength of the subfloor
b.The fire rating of the assembly
c.Indoor air quality for building occupants

Giải thích
Low-emission certification limits the chemicals resilient flooring releases into the air, so the goal is protecting indoor air quality and occupant health. Subfloor strength, fire rating, and seismic resistance are governed by other, unrelated provisions.
