What is the purpose of the “Track Changes” feature in Word?

The "Track Changes" feature in Word is specifically designed to monitor and record edits made to a document by different users. This feature allows authors and collaborators to make amendments, suggestions, and comments while maintaining a clear record of all changes. When enabled, any modifications, such as insertions or deletions, are highlighted, making it easy for the original author or other reviewers to see who made each change and to assess whether to accept or reject these suggestions. This collaborative aspect is essential in environments where multiple users might be working on a document, as it facilitates feedback and discussion about the content.

The other options, while useful features in Word, do not share the same purpose as "Track Changes." Formatting text in bold focuses only on typography without tracking edits; changing the document layout involves structural adjustments, while inserting footnotes is a method of adding citations or references rather than monitoring content changes. Therefore, the primary utility of "Track Changes" centers on documenting edits and facilitating collaboration among users.
