Explain one benefit of quality control for ABC's recovered metals.

• A. Reduces variability in purity
• B. Ensures the recovered gold meets purity standards
• C. Increases processing time
• D. Adds unnecessary costs

Answer: (B)

Quality control aims to make sure products meet defined standards by testing and verifying samples. For ABC’s recovered metals, this means checking the gold’s purity to ensure it matches the specified fineness. The strongest benefit is that the recovered gold meets purity standards, which gives customers confidence, supports pricing and market acceptance, and helps avoid penalties or returns from selling substandard material. While quality control can also help reduce variability in purity, the direct, most important outcome in this context is consistently meeting the stated purity standards. The other options describe costs or time increases, which aren’t benefits.
