Final answer:
In OpenOffice Writer, if you do not agree with a tracked change, you should select 'Reject' to decline the revision. Use the Previous and Next buttons to navigate changes and ensure to save after making your edits.
Step-by-step explanation:
If you are using OpenOffice Writer and do not agree with a tracked change in a document, the option that you should select is Reject. The Reject feature in the tools ribbon is used to decline any revisions you do not want to incorporate into the document. This contrasts with the Accept option, which you would use to approve a change that you agree with. It is important to review each tracked change individually to avoid unintended alterations to the document; thus, you should use the Previous and Next buttons to navigate through changes consecutively.
Once all of the changes are addressed, all edits should be either accepted or rejected, and any lingering comments deleted, to ensure they do not appear in the final version of the document. After making your revisions, do not forget to save the document to preserve the changes.
