Answer:
Well-defined characters suggested by actual experience
Step-by-step explanation:
One of the key elements in realistic fiction is the presence of a character that has flaws, contradictions, virtues, and faces a psychological or physical struggle, and endures impactful events that change him/her and shape the person he/she is.
All of these features help the reader empathize and connect with the character because they represent life-experiences that any person may have encountered or faced.
