Answer
# Brief Explanations:
The conclusion of a paper wraps up the discussion, giving a sense of completion or closure. It's not necessarily about a lesson or moral (which may apply more to some narrative - type works), the main theme is usually presented throughout the paper, and the plot is relevant for narrative - based works, not typical academic or general papers.
# Answer:
D. closure
