Answer 1

The best option to prove the authenticity of a file in a workbook is a **digital signature**.

While watermarks and encryption can serve specific purposes, a digital signature provides a way to verify the identity of the sender and to ensure that the content has not been altered, thus proving authenticity. Version control is primarily for tracking changes and managing versions, rather than proving authenticity.
