B plz mark brainiest when you have the time.
"Autobiography" means a biography of oneself, that is, the author is describing their own past and their own life.
When you describe your own life, typically you would write it in the first person ("I") and this is also true for Barrio Boy.
The letter following the quotation needs to be capital. This is because what the person said is also a sentence.
Example: As Mark was walking he said, "This is a beautiful day!"
