Answer:
C. By blending historical facts with imaginary characters and plots.
Step-by-step explanation:
Works of historical fiction are works that revolve around the theme of historical facts and truths from which a writer can base his/ her work. And as such, writers use historical themes and ideas as background for their stories.
When historical facts are used or incorporated in a fictional story, it gives it the feeling of authenticity, and greater importance, as in dealing with a historical event. It exudes a sense of 'heroism' of the characters, making the story more interesting. So, the incorporation of imaginary characters and plots with historical facts allows writers of historical fiction to present an appealing work.
