The topic sentence is, of course, a sentence where you state the main topic of your paper. You want people to know your topic as soon as possible. Therefore, answers A and D are obviously places you would most commonly put your topic sentence. However, you can also put it in your body of your paper. But the one place you never want to put your topic sentence is answer C, in your conclusion paragraph.
I definitely can't answer for your personality lol<span />
Repetition: Allows the audience to understand the message of the text because it is repeated.
D should be the answer: <span>brought in; concluded
</span>
C is considered to be a sentence fragment because it looks like a sentence but it isn't.
