Answer: A
Correct answer: produce many personalised documents from one template and a data source
Mail Merge combines a main document - a letter, label sheet or envelope containing merge fields - with a data source such as a Word table, an Excel worksheet or an Outlook contact list, producing one personalised copy per record. The process has three parts: writing the main document, connecting the data source and inserting the fields, then previewing and completing the merge. Fields such as «FirstName» are replaced by the value from each record in turn. It is more capable than simple substitution. Rules allow conditional text - an If…Then…Else field can vary the wording by record - and recipients can be filtered or sorted before merging. The third option describes an entirely different feature, Combine or Compare, used to reconcile two versions of the same document. Mail Merge is most often used for form letters, mailing labels, envelopes and certificates.
