Answer:
The correct answer is C. a supernatural theme.
Explanation:
Gothic literature refers to the type of writing that employs dark, melancholic, gloomy themes, supernatural elements, horror, fear, darkness, etc. In the excerpt above, we can see that the narrator just saw an apparition, a ghost of her dead mother who died five years before. This element is obviously supernatural, as ghosts aren't real. But this theme fits Gothic writing perfectly.
Some famous Gothic writers include Edgar Allan Poe, Mary Shelley, Bram Stoker, Victor Hugo, and many others.
