Answer: C

Explanation:

The metal base, 20% of product by weight, which do not contain heavy metals and is not plated with hexavalent chromium, contributes toward Materials and Resources Credit, Furniture and Medical Furnishings. This is because it meets the criteria of Option 1: Minimal Chemical Content, which requires that all components that constitute at least 5%, by weight, of a furniture or medical furnishing assembly must contain less than 100 ppm of at least four of the five chemical groups listed in the option. The other portions of the product either do not meet the 5% weight threshold (wheels), or contain chemicals that are restricted by Option 1 (fabric, armrests).
