Chuck tells his son Jeff that it's complicated to explain what a "muscle car" is. But, Chuck says, "the best example of a muscle car from the 1960s is the Mustang." Chuck has explained this concept of the muscle car based on using the. a. Exemplar Modelb. Representativeness Heuristicc. Prototype Modeld. Availability Heuristic

Prototype model

Explanation:

The prototype model is related to our prototype built in our memory related to the organization of things systematically. This model is closely related to our schema. The prototype is a system that is used to describe that whatever we perceived to have the complete image with qualities that are required.
