How is irony used effectively in storytelling?

Irony is an effective storytelling device because it often involves a contrast between what is expected and what actually occurs, particularly in the context of character awareness. When characters remain unaware of the truth while the audience understands it, this creates a layer of dramatic irony. This type of irony engages the audience, as they may feel a sense of anticipation or tension regarding the moment when the character will finally grasp the reality of their situation. This technique heightens emotional responses and can add depth to the characters and the narrative, as readers may feel sympathy or frustration with characters' ignorance.

In contrast, the other choices do not effectively capture the essence of how irony operates in storytelling. Predictable endings do not surprise or engage an audience, multiple narratives can create complexity but don't inherently involve irony, and adhering to traditional plot structures does not necessarily evoke an ironic twist or reveal.
