It helps you imagine what they're doing in the story
A. a true story written about a real person by someone
A biography, or simply bio, is a detailed description of a person's life. It involves more than just the basic facts like education, work, relationships, and death; it portrays a person's experience of these life events.
P.S. the answer is NOT C because when you write a story about yourself it's called an autobiography, not a biography
What is this question asking exactly?
Using a reference to someone or something that is well known is called an A. allusion. Hope I helped!
