Which term describes a preliminary version used to test ideas before the final product?

• A. Algorithm
• B. Prototype
• C. Circuit
• D. Blueprint

Answer: (B)

A prototype is an early, rough version created to test ideas and get feedback before building the final product. It lets you explore how something might look and work, try out key features, and identify problems without the time and cost of a polished product. By testing with users or stakeholders, you can learn what ideas work, what doesn’t, and what needs to be changed, then iterate accordingly.

Other terms don’t fit as well in this context. An algorithm is a step-by-step procedure for solving a problem, not a physical or test version of a product. A circuit refers to an electrical pathway or a complete electrical system, which is about functionality rather than a preliminary model for testing ideas. A blueprint is a detailed plan or drawing for construction or manufacturing, serving as a design guide rather than a working early version used to test ideas.
