Which element is common in anything but is not found in all fiction
a. setting
b. character
c. supernatural
d. message or theme

supernatural.

This is because not all fictional stories are horror/supernatural, but all horror stories are fiction. A story must have a setting, character, and message/theme for exposition but it does not need a supernatural object/person in its passages. Hope this helps!
