Why might an author choose to use first-person narration?

First-person narration allows the author to present the story through the eyes and experiences of a specific character, often the protagonist. By doing so, it creates an immediate and intimate connection between the character and the reader. This perspective invites readers to experience the character's thoughts, emotions, and inner conflicts directly, fostering empathy and engagement with the narrative. Such a personal angle can enrich the reader's understanding of the character's motivations and the story's emotional undercurrents.

Option A, while it suggests an objective portrayal, is often contrary to the subjective nature of first-person narration, which is inherently tied to personal experience and perspective. Option C indicates complexity in the plot, which can occur with any narrative style but is not the inherent purpose of first-person narration. Lastly, option D implies a formal tone, which tends to contradict the often personal and informal nature seen in first-person narratives, as they tend to favor a conversational style. Thus, the choice that best reflects the advantages of first-person narration is the creation of a personal connection with the reader.
