Which option shows design use of form?

Understanding an object in three dimensions in a product model

The governing concept is the functional use of three-dimensional form in design. A product model must communicate an object’s volume, structure, surfaces, proportions, and often the way it can be held or used. Option A is correct because understanding an object in three dimensions helps the designer judge appearance, balance, construction, and usability before production. Option B concerns smell rather than visual form. Option C reduces the object to a mark with no useful structural information. Option D removes depth, which is essential for distinguishing form from a merely flat shape. In product design, form is not decoration alone; it connects visual appearance with physical organization and practical use. Sketches, mock-ups, and models allow these relationships to be tested from several viewpoints.
