Rob used track changes to suggest changes in jack's document. jack agrees with some edits and disagrees with others. what should jack do with the edits so that he has a clean copy of the document?
a.
click the reject changes icon on the reviewing toolbar and select reject all changes in document.
b.
click the next icon on the reviewing toolbar to review and then accept or reject each edit.
c.
click the accept changes icon on the reviewing toolbar and select accept change for each edit.

B.   Click the Next icon on the Reviewing toolbar to review and then accept or reject each edit.

Explanation:

Since Jack wants to keep some changes and reject others, he can't use  a global solution (like presented in answers A and C).

He has to go through each and every change proposition and decide individually if he wants to keep the change or not.  That's why it's answer B.

It's the only way to accept some, reject some.  

At the end of this process, he'll have a clean document with Rob's recommendations and his original documents.
