Which of the following statements is correct regarding page editing?

The statement that changes can always be undone is accurate in the context of many content management systems, including HubSpot's CMS. When editing a page, users often have the ability to reverse their recent changes through an undo function or a revision history feature. This provides a safety net for users, allowing them to experiment with edits without the fear of permanently losing earlier versions of their content.

The other options could give the impression that users operate under more rigid constraints. For instance, not being able to restore removed sections or needing approval from an admin could hinder the agility that marketers typically require in managing content. The presence of an auto-save feature, while beneficial, does not guarantee the same level of control over changes compared to an undo functionality, which is specifically about reverting actions rather than just saving progress. Thus, the ability to undo changes stands out as a core feature that empowers users during the page editing process.
