I would go with A. The others seem more scientific and simply answered. For an essay you're gonna want something with multiple answers. So I'd for sure go with A.
A. What reading skills are involved in reading graphic novels.
Explanation:
Narrowing a topic is very much significant to begin writing as a too broad or wide topic would be unmanageable and may create conflicting opinions. A research question would best aid to narrow down the topic and specify the area of research and carry it forward. At the same time, the topic should be comprehensive and effective for readers. Thus, the research question that would best complement to narrow the topic for a five-paragraph paper, would be "What reading skills are involved in reading graphic novels?" as this question would give a short, sharp, concise and effective form to the paper.
