D. Supporting evidence should be summarized.

In a conclusion, supporting evidence should not be introduced or explained in full detail since that is typically done in the body paragraphs. Instead, the conclusion should provide a brief summary of the main points and supporting evidence mentioned throughout the essay or argument. This helps reinforce the main argument and allows the reader to quickly recall the evidence that has been presented.
