Answer:
The Conclusion should begin with…
C. A brief reiteration of the main idea.
Explanation:
The purpose of writing a conclusion is to wrap up the presentation of your ideas. Therefore, a conclusion should never present new information or evidence, since that will only make it an extension of the text's body. The conclusion should restate what the author has said previously, focusing especially on the main idea or claim, but in a shorter way, with fewer words. For that reason, the best option is letter C. a brief reiteration of the main idea.
