B. Chronological Order
Biographies are commonly written with the earliest events being at the beginning and the latest events being at the end. For example, if someone was writing a biography on Michael Jackson, then they would write about his time in Jackson 5 towards the beginning of the book, and write about his latest album and passing towards the end of the book. Think of biographies almost like a timeline: always in the order of when the events happened. Hope this helps!
