Yes, you are correct. An autobiography, such as "A White House Diary," is different from a biography because it tells about the writer's life. Autobiographies are written by the individual themselves, sharing their personal experiences, thoughts, and reflections on their own life. On the other hand, a biography is written by someone else about the life of a real person, detailing their accomplishments, struggles, and significant events. So, option A is indeed the correct answer.
