D
Explanation:
It is strongly advised that in a conclusion you don't introduce any new points. An effective conclusion provides the reader with a sense of closure and serves to wrap things up. You should repeat the points you made in your body paragraphs but make sure not to bombard the reader with too much information
e.g. If you followed this structure in your body paragraphs. (Point) (Why it's important) (Statistics), you should only mention your point in your conclusion along with a brief summary of why it's important.
