The correct answer is C. The thesis statement and author’s purpose are clear
Step-by-step explanation:
In an essay and any other texts, the introduction refers to the main paragraphs or paragraphs in a text written by the author with the purpose to engage readers, present the general topic and the main points that a paper would develop. Because of this, in most effective introductions especially those of essays and argumentative papers the author presents a hook or statement that engages the reader; then introduces the general topic and finally states the thesis statement and the purpose of the paper usually by stating them explicitly and with precise and clear words, which allows the reader to know the content and purpose of the essay. This means the component of an effective introduction is that the thesis statement and the author's purpose are clear.
