The statement that best explains the aesthetic elements of a literary work is Aesthetic elements impart an artistic quality. Aestheticism has to do with beauty, with everything that is pretty and pleasing to the eye. So, aesthetic elements obviously has to do with art and making a literary work more artistic. They usually have no impact on characters, theme, or background of the story, but only on its artistic value.
My deepest apology if this is not what you meant. I would appreciate it if next time you put more detail. Thank you!
