Answer:
I believe it is C, "Short stories have singular plots, novels have parallel plots and subplots."
Step-by-step explanation:
In a short story, there is usually just one main focus with a handful of characters. These aren't meant to be complicated, and follow one storyline. A parallel plot is what you'd find in a novel. This is the kind of structure that involves separate and complex narratives that oftentimes link the characters together.
