Explanation

Version control systems (VCS) such as Git, SVN, or Mercurial are designed to track every change made to files over time - recording what changed, who changed it, and when. This creates a complete audit trail and allows developers to revert to any previous state. Answer A is incorrect: VCS does not prevent multiple users from working on the same file; in fact, it facilitates collaboration by merging changes. Answer C is incorrect: VCS promotes sharing and collaboration, not the opposite. Answer D is incorrect: VCS does not track data types - that is a concern of type systems or schemas. The core value proposition of version control is its change history and the ability to collaborate without losing work.
