Answer:
The answer is indeed letter D. in a thesis statement.
Explanation:
A thesis statement consists of one or two sentences that express the focus of a composition, that is, the topic or opinion the author will discuss. It serves as a guide to not only the author, but also to the audience, clarifying what they can expect to read about. For the author, it serves as map, so that the writing won't get lost or distance itself from the focus.
