Answer:
The correct answer is B: By sugarcoating events.
Step-by-step explanation:
The use of unreliable narrators became known in literature as a literary device around 1961, when the term was first mentioned. Basically, these narrators help the writer to generate a sense of mystery, and a desire in the reader to discover the truth, since at some point they learn that what the narrator has been saying, is not the truth. These narrators tend to be first-person narrators, although some have used the second and third persons. And aside from giving hints in certain portions of the story about the reliability of the narrator, an author may also make the narrator change in some way the true meaning, or the reality, of a truth, by adding falsehoods, or deviations, of the truth, so that the reader starts to wonder about the veracity of what the narrator is saying, versus the actual happenings in the story.
