Answer:
D) it speeds the pacing up.
Explanation:
In general, when dialogue occurs in a narrative, this leads to the story becoming faster. Therefore, the pacing speeds up. This is because dialogue tends to come faster than the author's descriptions of something. Moreover, when dialogue occurs, the story tends to move as quickly as the characters think and speak. Finally, through dialogue, authors tend to reveal new subjects and ideas, and these "surprises" move the plot forward.
