Which of the following is a hallmark of satirical literature?

Exaggeration is a hallmark of satirical literature because it serves to highlight flaws, absurdities, or contradictions within society, individuals, or specific ideas. By amplifying certain characteristics or behaviors, satirical works create comedic or critical effects that provoke thought and discussion among readers. This exaggeration can take various forms, such as hyperbole or caricature, and is fundamental to conveying the author's critique of the subject matter.

In the context of the other choices, while descriptive language enhances imagery and can be found in satirical works, it is not specific to satire itself. Chronological narrative focuses on the sequence of events and is a structural element that does not define satire. Mystical elements, while potentially present in other genres, do not typically characterize satirical literature. Thus, exaggeration distinctly marks the style and purpose of satirical writing.
