Fixing the organization of your writing occurs during
a. editing
b. pre-writing
c. outlining
d. revising

The correct answer is letter "A": Editing.

Explanation:

The process of editing implies improving a former draft, correcting mistakes, changing words to make sentences or ideas clearer, effective or more accurate. This process also includes reorganizing, adding or deleting words along a whole paragraph. It is a great tool since it helps the author have an overview of the final work before it is finally considered finished so it will be polished for the reader to understand clearly what the purpose of the author is.
