This question concerns types of irony. It is missing the answer choices. I have found them online. They are the following:
1. verbal
2. dramatic
3. situational
4. none of the above
Answer:
The situation described is an example of:
2. dramatic irony
Step-by-step explanation:
Dramatic irony happens when the audience knows something that the characters in a book, play, or movie, for instance, do not. A famous example would be what happens in Shakespeare's tragedy "Romeo and Juliet." We know Juliet is not really dead - she has taken a potion that slows down her pulse to pretend to be dead. But, since Romeo does not know it, he ends up killing himself.
The scenario described in the question is also an example of dramatic irony. We, the audience, know that the killer is in the house, but the character does not.
