The correct answer is D. It speeds up the pacing of the story
Step-by-step explanation:
The pacing in a story is defined by how fast or slow the story moves or develops. For example, if an author uses multiple details just to describe each scene the pace will be slow because the reader will only receive new information after a lot of details and each action will take more time. In this context, using simple and short sentences will make the pace faster because the actions described in the story will occur rapidly and the reader will get new information in almost every new sentence. Thus, the use of simple language and short sentences speeds up the pacing.
