The correct answer is D. Thesis

Explanation:

Most essays aim at developing an argument related to some specific topic, issue or situation guided by a thesis statement and a set of supporting details. In essays, the thesis statement refers to the sentence that expresses the topic of the essay and the position or viewpoint the author of the essay has in relation to the topic. This implies, in the thesis statement the author tells the reader what the essay is about and which specific point the author will argue about. These elements are presented at the beginning of the essay (introduction) in which the topic is contextualized and then connected to the author's position or point of view. Additionally, the main claim or thesis statement is developed through arguments and evidence during the body paragraphs and a final concluding paragraph is usually added. Considering this, the section of the essay that should contain the essay's topic and viewpoint is the thesis as it is this statement the one that tells the reader the topic and the viewpoint or position the author will develop during the text.
