The correct answer is: All of the above

The correct answer is 'all of the above'.
Poems, stories, playscripts
Imaginative writing will include poems, stories and play scripts. Because, poems are written when one felt emotional by seeing something, whatever it can be. Same as poems, stories and play scripts are also imaginative writing. No facts are needed to compose any of these. One's imagination is enough to write all those. Imagination will add beauty to the work produced out of imagination.
