What element of a magical realist story can the reader discover it's theme

I found the missing choices. These are:
A.) The use of character dialogue
B.) The use of supernatural elements
C.) The use of changing perspective 
D.) The use of characterization

My answer is B. 

The use of supernatural elements can help readers discover the theme of a magical realist story.

A magical realist story is a narrative story that is almost similar to other fictional story with the difference of having supernatural or magical characters as part of the story. Magical realism is also called fabulism referring to myths and fables.
