Answer:
best example of a particular category.
Explanation:
A prototype can be defined as an early release or model of a product that has been built to practicalise a concept or process. A concept can be defined as a collection of similar ideas, objects, or events. For example an office chair, dentist chair, and barber chair are all for seating.
When you have a prototype you can compare new items with the prototype so that they can be grouped into categories.
Prototype is the original model of a product, that determines future versions of that product. That is future products are patterned according to the prototype.
