The best example of pastiche among the options provided is:
B. a film poking fun at a novel by mimicking it in an exaggerated way.
Pastiche is an artistic work that imitates the style of another work or artist in a humorous or exaggerated way. In this case, the film is mimicking a novel in a way that pokes fun at it, which aligns with the concept of pastiche. The other options do not directly fit the definition of pastiche as they involve elements of fantasy or imitation of a specific author's style without the comedic or exaggerated aspect typically associated with pastiche.
