D. A genre called fan fiction

D.

Explanation:

Fan fiction is a genre of fictional writing written by fans and posted on internet. The fans mostly base their work on already existing work or 'original' work and edit some parts by adding some other characters, events, and places that are not found in the original piece of art. This 'original' work can either be a book, movie, and the like. Fan Fiction is also known as fanfic, fan fic, or ff. It is a new genre coined in 20th century.

So, it is this new genre called fan fiction that allows readers to change and explore known literature. Therefore, option D is correct.
