Answer:
The correct answer is: "d. all of the above".
Explanation:
It is usually advised to do a speech conclusion which makes reference to the central idea by different ways, that is to develop a conclusion by different possibilities, whether by ending with a quotation and explaning its relation to the main idea, or by a dramatic statement which sets a final point to the major idea previously developed, or even by referring to the introduction as a way of reviewing the most important ideas related to the thesis of the speech. All ideas and informations must be connected and the beginning, central development, and final thoughts must be all linked in order to make sense and reinforce the central idea.
