I think the answer is B. :)
The clearest example of metafiction is the story. A story with footnotes that comment on the author's process.
Many resources can be employed to make use of metafiction (a narrative technique in which the author constantly reminds the reader that he or she is reading a fictional work), and some of them include:
- Telling a story within a story
- Telling a story about a third person who's reading or writing a book
- And of course, telling a story and making use of footnotes to comment on it
In this way the reader is engaged and becomes a participant in the story, forcing himself to think about the nature of the narration and how much credibility exists in the stories he/she reads.
