13. Freewriting is an exercise in which you A. rewrite an article in a magazine or newspaper. B. write only grammatically correct sentences. C. write whatever thoughts come to mind. D. revise and polish an essay.

The answer is C (write whatever thoughts come to mind) because it is where a writer just is letting everything flow onto their paper without worrying about anything else except for what ideas need to be put onto paper in that exact moment.
