How does a reader determine the credibility of a narrator?
a) by evaluating whether or not the narrator is actually the speaker
b) by determining whether or not the narrator is the same as the author
c) by examining the balance and consistency of information provided by the narrator
d) by judging if the narrator is realistic enough to trust

The correct option is C

The narrator is the voice that tells and recounts events, stories or anecdotes. In the case of the narrator in the first person (internal narrator or protagonist), the narrator is a character within the story (intradiegetic): acts, judges and has opinions about the facts and the characters that appear. In this case the narrator only has and provides information based on his own vision of the events. But we also have other narrators like the one who is in second or third person, the omnipresent, among others.
