• A. Model
• B. Replica
• C. Diagram
• D. Prototype

Answer: (A)

A three-dimensional representation of a real object reproduced at the original size or to scale is called a model. This term emphasizes a tangible, scaled or life-size stand-in used for study, demonstration, or visualization of how the object looks and works without needing the full-size version. A diagram, being two-dimensional, shows information in flat form rather than a real object. A replica is a faithful copy of the original, which can be 3D but is focused on exact imitation rather than a scaled or educational stand-in. A prototype is an initial version of a product used for testing and development, not primarily for display or teaching about the object.
