Answer:

  (b)  tangible approximation of the product that often look and feel like the product

Step-by-step explanation:

"Physical" means it exists as an object in the real world, not just as a model on a computer screen. "Prototype" means it is an approximation of the finished product, lacking in one or more details of appearance, structure, or functionality.
