Personal life or first-person point of view is a characteristic of fictional adaptations of autobiographical works.
An autobiography is a fictional piece of work, which means that the events described in it have to be based on true events, and it is written by the same person whose life is being described in the book. So, its main characteristic is that it describes the personal life of someone who writes it using first-person point of view. The rest of the options can be included in an autobiography but they are not a characteristic of this literary genre.
