What must you do to save changes to a document before sharing?

To save changes to a document before sharing, you simply need to select the Save option. This action updates the existing document with any modifications you have made, ensuring that your changes are preserved.

When you save the document, it writes the latest version with all edits to the file, so it is ready for you to share with others. Saving is typically done by clicking on the Save icon or using keyboard shortcuts, depending on the software you are using.

While other choices might have specific uses, they do not directly fulfill the requirement to save changes effectively. For instance, 'Save As' is typically used to create a new file or save an existing file under a different name or location. The 'Print option' is for producing a hard copy of the document and does not save changes. The 'Export' function is often utilized to save the document in a different file format but may not necessarily save changes in the original format. Thus, using Save is the appropriate action to ensure all alterations are kept intact before sharing the document.
