Dramatic irony occurs in a story when the audience knows something about the actions of an actor that the characters do not know about. An example of dramatic irony in this story is;
D. Through the character of Feste the Clown pretending to be an authoritative figure
In that story, we see that Feste the clown pretended to be a priest and went to the prison where Malvolio was held to question him.
So while the audience knows that the person interviewing Malvolio was not a priest, Malvolio did not know this fact.
Therefore, option D is an example of dramatic irony.
