i think it's d

Answer 3

None of these people are explaining the answer, so I will explain.
A is correct. You should review your main points because it reminds the audience that "Hey! This is what we've covered!"
B is also correct. By summarizing your argument, you are reminding them why you feel that way.
C is correct. You should make a lasting impact on your audience, especially if you are trying to persuade the audience to feel the same way you do.
D is incorrect. Why? Because your sources should be cited all throughout the document (parenthetical citation), and in your bibliography. Not in the conclusion.
