mary shelley is not the answer, because it says "pick the ones you can write a SHORT research paper on" when the first one says in depth study of marry shelley's book, frankinstein, meaning it would be alot longer then what its asking for.
the correct answer would be c & d because they are both analysis, meaning its basically making a summary about the topic, and those are not long.
I'd say just Mary Shelly's Frankenstein, as the others seem to be self-contained, demanding no research. Meanwhile, researching Mary's life and her era all give ample background as to the influence and history leading to the novel inventing the genre of science fiction.
