Writing the introduction of a book or paper is a crucial step, whether it's done first, last, or during the drafting process. It serves several purposes: to engage the reader, to provide context, to outline the main points, and often, to present a thesis statement which previews the book's or paper's main idea. It's important that the introduction captures the readers' interest and compels them to continue reading. It's the author's chance to establish the right context for the readers and clarify any relevant assumptions about the subject or the audience they expect.
The correct option that defines the beginning section of the book designed for this purpose is option a) introduction.
