What distinguishes first-person narration from third-person narration?

The correct answer highlights that in first-person narration, the narrator is a character within the story, often identified by the use of pronouns such as "I" or "we." This perspective allows the reader to experience the events, thoughts, and feelings of the narrator directly, creating a deeper emotional connection to that character's experiences.

In contrast, third-person narration typically involves a narrator who is outside the story and refers to characters using pronouns like "he," "she," or "they." This type of narration can provide a broader perspective, but it does not include the personal, subjective experiences that come with a first-person viewpoint. Therefore, the key distinction lies in the narrator's relationship to the story: being a participant versus being an observer.
