In evaluating quality, the key criterion is the product's?

• A. Cost
• B. Appropriateness for product use
• C. Color
• D. Brand

Answer: (B)

Quality is measured by how well a product fits its intended use and performs as expected. The key criterion is whether the product is appropriate for its use—whether it meets the purpose it’s designed for under the conditions it will face. When a product truly fits the use, it supports the required performance, safety, and reliability, which are essential aspects of quality. Cost, color, and brand may influence value or perception, but they don’t determine whether the product will perform its intended function. So, appropriateness for product use is the best indicator of quality.
