A. set against a historical backdrop
The correct answer is - it's set against a historical backdrop.
Historical fiction, as the name itself states, is a fictional writing (so, not real) that takes place in history. So, it can be based on real-life events, however, it is usually not completely historically accurate. It can tell tales about the lives of famous historical people, things that nobody could possibly know - but it's fiction, so anything is permitted.
