Which term describes a single article that can be used as a prototype before mass production?

• A. Paper-based rapid prototyping
• B. Multi task robots
• C. Particle boards
• D. One-off production

Answer: (D)

A single article used as a prototype before mass production is described by one-off production. The idea is to create just one unit to test form, fit, and function, and to work through manufacturing steps without committing to a full run. This lets designers validate the design and the production process before investing in tooling for large-scale production. The other terms refer to different ideas: paper-based rapid prototyping is about quick concept models, not a single final unit; particle boards are a type of material; multi-task robots describe capabilities of machinery. So one-off production best fits the description of a single article used as a prototype.
