Answer:
C
Explanation:
i would say C because
A is an opinion and thesis statements aren't supposed to be opinions if it's for research. your opinion isn't supposed to be given and the word I shouldn't be involved.
B wouldn't be a good research idea, plus I'm not sure it's even true.
D us more of context or more of a fact if it's true.
so the logical answer is C because u can research the parallels in the stories and it requieres actual research
