Answer:
D. All of the choices
Step-by-step explanation:
All of the listed choices are crucial to an effective conclusion.
Stating the topic of your conclusion in clear language helps to reinforce the main idea of your writing.
Restating your thesis differently but with same meaning also serves to emphasize your main idea throughout the essay, while not boring the reader with exactly the same words and showing sophistication.
Restating the main points and relating them helps to finalize your ideas to the reader and demonstrate how they all connect to one other once and for all before your essay ends.
Hope this helps!
