Answer:
C. The narrator describes the trials of the family in a grim, judgmental way.
Explanation:
In literature, the "voice" of a story represents the narrator's form of expression, where he expresses his emotions, positions and opinions in relation to the story being told. In this case, we can say that when the narrator decides to criticize the family's trials, he expresses a feeling of discontent, thus being an example of a "voice" in history.
