Which component is essential for handling sensitive documents to track changes over time?

• A. Publicly accessible folders.
• B. Version control with restricted access and backups.
• C. Delete old versions immediately.
• D. Rely on memory.

Answer: (B)

Version control with restricted access and backups is essential for handling sensitive documents to track changes over time. It records every modification as a separate snapshot, showing exactly what changed, when it happened, and who made the change. This creates a complete, auditable history you can review, compare differences between versions, and even revert to a previous state if needed. Adding restricted access keeps the document confidential by ensuring only authorized individuals can view or edit it, while backups protect against data loss from accidents or hardware failures. Together, these features provide accountability, recoverability, and integrity for sensitive materials.

Choices that rely on publicly accessible folders lack proper access controls and do not provide a reliable change history. Deleting old versions eliminates the ability to trace edits over time. Relying on memory offers no verifiable record and is prone to errors.
