A biography is distinguished from an autobiography primarily by the authorship. In a biography, the subject's life story is narrated by a different person, often providing an external perspective and researched insights into the subject's life, achievements, and contributions. This allows the biographer to present a more comprehensive view of the subject, often including information that the individual may not have been aware of or may choose not to include in their personal narrative.

On the other hand, an autobiography is a self-written account of one's life. The author shares their own experiences, thoughts, and reflections, giving a personal insight that only they can provide. This distinction in authorship is critical because it shapes the narrative style, perspective, and depth of the information provided. The other answer choices do not accurately capture this key difference, as they misrepresent aspects of biographies and autobiographies, such as fictional content or the nature of the characters discussed, which aren't relevant to the definitions of these literary forms.
