Explanation:
A thesis statement can be comprised of one or two sentences expressing the author's opinion on a topic or subject. It usually appears at the beginning of the paper, often at the end of the first paragraph. A thesis statement should not offer arguments or evidence to support the author's opinion. That should be done as the body of the text is developed. Having that in mind, we can eliminate options A, B, and D. Only letter C has the characteristics of a thesis statement. Option A presents a type of conclusion, and options B and D present arguments.
