What is the role of version control in CSS Block 2 documentation?

• A. It encrypts all documents
• B. It reduces data size by compression
• C. It automates data entry
• D. It tracks changes, maintains historical records, and prevents confusion from outdated information

Answer: (D)

Version control serves as the record-keeping system for your documentation. It records who made changes, what was changed, and when, and it stores a complete history of the document. In CSS Block 2 documentation, this lets multiple authors collaborate smoothly, review and compare different edits, and rollback to previous versions if something needs fixing. It keeps everyone aligned by making outdated information easy to identify and update, reducing confusion and maintaining consistency across the docs. It’s not about encrypting content, compressing files, or automatically entering data—those are different functions and not what version control provides.
