D. adventurous and fantastical episodes

Respuesta :

I would say A) everyday life & common subjects.
the theme would be A. . everyday life and common subjects 
Artists and writers during realist era love to create something that represent a certain situation truthfully, without adding any false/extreme narrative to attract attention or any supernatural element. 
So, most of their works revolves around 
everyday life and the problems that normal people experience.
