Which term best describes a preliminary sketch or model used before building the final product?

• A. Prototype
• B. Diagram
• C. Specification
• D. Deployment

Answer: (A)

This question is about using an early, tangible representation to explore and test ideas before building the final product. That is a prototype. A prototype is created to experiment with how something might work, look, or feel, and to gather feedback so you can refine requirements and design choices before committing to full development. It helps reveal design flaws, clarify user needs, and guide decisions on features, cost, and feasibility in a concrete way. A diagram is a visual plan or flow of how something should function, but it isn’t necessarily a working or interactive model. A specification is a detailed description of requirements and constraints for the final product. Deployment is the act of releasing the finished product to users. While diagrams and specifications are important, they don’t provide the early, testable model that a prototype offers.
