The correct answers are A. The narrator can be a witness or a reteller of events and D. The narrator is a character in the story
Step-by-step explanation:
In literature, a first-person narration occurs when the story is told by one of the characters involved in a story or a witness that uses the pronouns "I" or "We" rather than the pronouns "she", "he" or "it" as in the case of the third person narration. This means in first-person narration the narrator is generally involved in the story and the events are told from his/her perspective, also this narrator can know everything about the characters but generally is limited and does not have access to all the information or all the events. Also, most of these narrators are classified as unreliable, which means they do not provide completely accurate information.
Therefore, the statements about first-person narration that are true are "The narrator can be a witness or a reteller of events" as the first-érson narrator is someone that reports the events he/she witnessed or the events in which the narrator was involved and "The narrator is a character in the story", because the narrator can be directly involved in the story and therefore becomes a character and not only a narrator.
