B because it doesn't have to much thought to it. It sounds plain and simple.
You didn’t put a picture of the passage so there’s no way to know which one. So I’ll just give you info about each topic
ANSWER: If it’s a NARRATIVE passage then it’s a story probably using fictional language describing a made-up story about a car and a dog.
ANSWER: If it’s a PERSUASIVE passage then it’s not a story it’s a passage trying to convince you to do something or think something.
So if it’s a story it’s narrative if it’s trying to convince you of something it’s persuasive.
Hope this helps !!
