The correct answer is D. To organize your prewriting work
Explanation:
In writing, an outline is a plan or summary of the contents or key ideas that would be included in a text. Because of this, outlines are used as an effective strategy during the prewriting stage as this tool allows writers to organize the content of a text before writing the first draft and in this way avoiding omitting or repeating ideas. This means by using an outline the writer will have a coherent text as in this way all the content is planned and organized before and thus, the purpose of an outline is to organize your prewriting work.
