What is version control and give an example of a tool.

• A. Version control tracks changes to code and documents; examples include Git, SVN.
• B. Version control stores only binary assets.
• C. Version control automatically fixes bugs.
• D. Version control handles user authentication.

Answer: (A)

Version control is the practice of tracking and managing changes to code and documents over time. It records who made each change, when it was made, and why, so you can review history, revert to earlier versions, and collaborate without overwriting work. It also supports branching and merging, which lets teams work on features separately and then combine them smoothly.

An example tool is Git. Git is a distributed version control system that uses commits to record changes, supports branches for separate work streams, and enables merging teams' changes efficiently. It helps you see the full history of a project and manage multiple strands of work in parallel.

The other statements don’t describe version control's purpose. It isn’t about storing only binary assets, automatically fixing bugs, or handling user authentication. Those are separate concerns or tools outside version control’s primary function.
