Answer:
B. Unreliable narrator
Step-by-step explanation:
The unreliable narrator in fiction is the character that tells the story in the first person, but their view of the events not trustworthy. Authors of the story have a different interpretation and account of the events than the one presented by their narrator.
The character’s through which voice we hear the narrative can be intentionally hiding the information, or simply have a twisted understanding of the actions and events. For example, in Vladimir Nabokov’s Lolita, the character telling the story doesn’t see his wrongdoings as he has a self-delusional idea of reality; in Room by Emma Donoghue, the narrator is a little boy, so he can’t understand all the events and the reader sees everything as he does. Authors of these stories know what's happening and what are the "real" events, but he deliberately tells the story through different lenses to the reader.
