Which device is used to create a humorous imitation of a style?

The device that is used to create a humorous imitation of a style is a parody. A parody takes the characteristics of a specific work, genre, or style and exaggerates them in a way that is intended to be funny or satirical. This technique allows the creator to comment on the original work, often highlighting its flaws, conventions, or absurdities in a light-hearted manner.

Parody is commonly found in literature, film, and other forms of art, where familiar tropes or patterns are mimicked and then twisted for comedic effect. This device not only entertains but can also provoke critical thought about the original material by presenting it through a skewed lens.

In contrast, the other choices do not fulfill the function of humorous imitation. Chiasmus involves a specific rhetorical structure where elements are reversed in successive phrases, anaphora refers to the repetition of a word or phrase at the beginning of successive clauses, and extrapolation involves drawing conclusions or extending predictions based on existing data. None of these devices inherently aim to mimic styles for comedic purposes like a parody does.
