Answer:
The time and location. (A and B)
Step-by-step explanation:
A story's setting is where the story takes place. The time and location are two very important factors to the setting of the story. If the story is a si-fi story, then it might be set in the future, as with a western story it would be set in the past.
Theme and characters deal more with the plot of the story than the setting.
