Answer :
The correct answer is D. Revising paragraphs for clarity
Explanation:
The writing process is usually composed by five main stages each of them with specific tasks, steps, and strategies that help the writer to complete the process of writing successfully and achieving a specific writing task by the end of the process; these stages are prewriting, writing, revising, editing and publishing. In the case of the pre-writing stage, this is the first stage in the writing process and it is about preparing for writing, this includes deciding on the topic that you will write about through brainstorming or discussing with a peer; looking for information about the topic by searching on internet or looking for information in a library and planning the contents of the text. This implies the one that is not an activity that is part of the prewriting stage is "Revising paragraphs for clarity" because the prewriting stage is about preparing for writing and for revising paragraphs it necessary to have already written a draft of the text which is not part of the pre-writing stage.
