Which of the following is an example of dramatic irony?

Dramatic irony occurs when the audience knows more about a situation than the characters do, leading to a deepened emotional experience as viewers anticipate the character's reactions when they eventually uncover the truth. In the scenario where a character believes they are safe while the audience is aware that they are actually in danger, the tension and suspense are heightened. This creates a poignant disconnect between the character's understanding and the audience's knowledge, which is the essence of dramatic irony.

The other options do not fit this definition. An unexpected gift may surprise a character, but it doesn't involve the audience's prior knowledge creating a contrast with the character's understanding. A twist ending can be surprising but is not inherently dramatic irony unless it plays off the audience's previous understanding. A repeated theme adds depth to the story but does not involve the interplay of knowledge between the audience and character that defines dramatic irony.
