(A)
The choice of narrator totally affects the characterization available.
The narration can be done in first or third person, so we can classify the narrators as narrator in 1st person and narrator in 3rd person.
Narrator in first person is the character narrator. In addition to telling the story in the first person, it is part of it, and is therefore called a character. It is marked by subjective characteristics, opinions in relation to the events that occurred, and thus a partial narrative, since no other angle of vision can be seen.
The third-person narrator is the omniscient narrator or the observer narrator.
The omniscient narrator is the one who knows everything. There are several types of omniscient narrator, but we can say that they are so called because they know all aspects of the story and its characters.
The observer narrator is what introduces history, but unlike the omniscient does not have the vision of everything, but only from an angle. He behaves like a witness to the facts reported, but he is not part of any of them, and his only attitude is to reproduce the actions he sees from his angle of vision.
