This question is missing the options. I've found the complete question online. It is as follows:
Thomas is fascinated by the play he is reading. He knows something about what has happened that the main character doesn't realize yet. Which literary device is the author using?
A. understatement
B. hyperbole
C. dramatic irony
D. symbolism
Answer:
The literary device that the author is using is C. dramatic irony.
Step-by-step explanation:
Dramatic irony is a literary device used by authors to reveal to readers something that the characters themselves do not know. A classical example of dramatic is found in Shakespeare's tragic play "Othello", in which viewers and readers are aware of Iago's wickedness. Othello himself, as well as the other characters, do not know Iago is manipulating all of them. They trust him blindly. Readers, however, get to "watch" Iago concoct his evil plans.
