Answer:
B. The author goes back and forth between first and third person.
This sentence describes the use of first and third-person narration, which is a key aspect of the author's voice rather than style. Voice refers to the author's unique perspective and tone, while style refers to the way in which the author uses language and literary devices to convey meaning.
Step-by-step explanation:
The sentence "The author goes back and forth between first and third person" is an example of a voice-related description because it describes how the author chooses to narrate the story, and the use of first and third person point of view can have a significant impact on the reader's experience of the story. In contrast, the other options are more focused on aspects of style, such as the use of dialogue or pacing, which are important but are not the same as voice.
