The correct answer is B.
The way a conflict is resolved usually suggests something about the theme.
For example, let's say a theme is "truth." If a conflict has a positive resolution, that says something different than if it has a negative resolution. A negative resolution to a conflict might indicate truth is painful, while a positive resolution to a conflict might indicate truth is necessary and/or healing.
