The author suggests that a prototype is constructed using similarity... then in the pizza example, suggests that inductive inference looks at similarity between an object and a description. So they do sound like similar processes. But, I think I would have approached this question by eliminating the answer choices that do not make sense or are unresponsive to the question. A - eliminated because the author did support it with the pizza example; B - eliminated because the author did demonstrate knowledge of these concepts; C - sounds like the prototype construction so I kept this; D - the size of quarters was not important, but the similarity between objects.
