The correct answer is D- A narrative tells a story, while expository writing contains only fact-based information.
A run-on sentence is a sentence having two independent clauses with improper punctuation and without conjunctions. The correct answer is option b. It is difficult to understand a run-on sentence because you cannot identify where to pause or stop and that the sentence does not have conjunctions which would help in the transition of clauses.
I would say B. C could also be an option, but I think B makes the most sense :)
