The inference that is best supported by the passage is:
A. The writers of successful films learned from the plot structure outlined in Campbell's book.
Explanation:
When the author of the passage mentions movies such as "The Matrix", "Star Wars" and "Lord of the Rings", the purpose is to show how important and effective Campbell's structure is. It is not that those movies plagiarized anything. And it is not that Campbell analyzed those movies. It is just an archetypal structure, that is, a structure that can be found almost universally and that is effective precisely because it is understandable. The author does not say that a movie that does not follow that blueprint will be a failure. There are movies that do so effectively and are acclaimed for that. But, whether we like it or not, most successful movies - at least the Hollywood ones - do tend to follow that blueprint with a high degree of success.
