Like the work of other authors of her time, Mary Shelley's work features: (a) character who fall from glorious accomplishment to grave dishonor (b) allusions to literary works that readers have not read, (c) criticisms of scientists who failed to respect the power of nature, (d) formal language and elaborate descriptions

I think the answer is letter A. character who fall from glorious accomplishment to grave dishonor

All her stories circles on alienation and regret. One of her famous work is Frankenstein. Frankenstein is a story of a man who defies the law of nature and regrets creating a monster. Frankenstein lived in alienation and regretted for creating something that was bound to kill him one day.
