Answer:
C. By blending historical facts with imaginary characters and plots.
Step-by-step explanation:
Historical fictional works are those works that revolve around historical facts and the themes and stories contain details about such historical facts. In such types of works, the writer uses historical facts as a backdrop or background for his or her work and lets the story work its way according to it.
In such works, the use of historical facts makes the work great work when infused with historical characters and themes. Moreover, it also provides a sense of heroism in the characters. And in blending the historical facts with imaginary characters and plots that will flow well with the history, writers can appeal to the readers.
