Answer:
A) Editing and proofreading.
Explanation:
They are both stages of the revision process, sometimes they are used as interchangeable terms but they focus on different aspects of the writing.
Editing is what you do when you finish the first draft. Reread it to see if the paper is well-organized, the evidence really backs up the argument.
Proofreading is the final stage of the process, is more focused on surface errors like misspellings and mistakes in grammar and punctuation.
