The correct answer is: Option D. The pace of the writing slows.
A compound sentence is a connection between two main clauses, which are joined by a conjunction.
A single clause may be either independent or dependent. A independent clause makes sense in its own, whereas a dependent clause can't make sense without the prior context of an independent clause. Therefore, only an independent clause can be considered a complete clause.
When these two concepts are inserted into a work of literature, the level of detail in the story is extended. Thus, the reader gets more content to process, and the pace of story-telling is slowed.
