The correct answer is option A.
In a literary work, MOTIVATION is the reason for a character's feelings, thoughts, and actions. As the story unfolds, the reader realizes why the characters behave in a particular way. For example, in the short story "The Mortal Immortal" by Mary Shelley, the main character "Winzy" takes a magic potion because he wants to overcome his love's suffering. Hence, motivation is the answer to the question of why the character does or does not something.
