The correct answer is D: introduction. The introduction is the part of an informational essay that introduces the main idea or topic. It typically includes a hook or attention-grabbing statement to draw the reader in, provides background information or context related to the main idea, and ends with a clear and focused thesis statement that states the main point or argument of the essay. To find this information, you can read the opening paragraphs of an essay and look for statements that introduce the main idea or topic.
