There are many types of narrators in a story. In general terms, they can be categorized as characters in the story line, that is the first-person view narrator; second-person view (in which the reader is addressed directly as if he or she was a character in the story); and third-person view narrator, which recounts the thoughts, feelings, emotions and events of characters within the story, but is usually not part of the story. From this last category, the third-person view narrator, there is one type of narrator that can be called the “third person limited” narrator (in contrast to a third person omniscient narrator) that only conveys the thoughts, feelings, and emotions of some characters in a fragmentary manner and without being part of the story.
A narrator who is not part of the story and only knows the particular portion of thoughts and feelings is the third person limited. The correct answer is C.
