Answer:
I think the answer is A...
Step-by-step explanation:
Non-fiction is prose writing that is based on facts, real events, and real people, such as biography or history.
B, order is a way of arranging actions, events or things according to the time they occurred. It is demonstrated by showing what happened first, what went on next, what came about in the succeeding occurrences, and until what took place last. This manner of presentation is also called time or linear order... I don't think so.
C, in fiction, cause and effect helps maintain plausibility in plotlines. While things may appear to happen 'out of a clear blue sky' in real life, in fiction there is almost always a reason (the cause) for the things that happen (the effect).
D, character traits can be in non-fiction as well, all people in biographies have character traits.
