Which statement best describes the use of a prototype?

• A. Marketing the product to customers
• B. Drafting the user manual
• C. Testing actual performance and making adjustments
• D. Final quality inspection after production

Answer: (C)

Prototyping is used to verify how a design actually works and to drive improvements. Building a prototype lets you test performance, behavior, and usability in real or realistic conditions, gather data, and make adjustments before committing to full-scale production. This iterative testing helps catch issues early and refine the design. Marketing the product to customers is about promotion and market feedback, not testing the design’s performance. Drafting the user manual happens later, after the design is stable enough to document, and final quality inspection after production checks a finished, manufactured item—not the iterative testing phase that prototypes support.
