Which statement best describes version control for a teammate new to the concept?

• A. It is only a backup tool and has no collaboration benefits.
• B. Version control tracks changes over time, supports collaboration; cover basic commands (clone, commit, push, pull) and branching.
• C. It is a physical device for storing copies of files.
• D. It automatically writes code for you.

Answer: (B)

Version control is a system that tracks changes to files over time and enables collaboration among teammates. It records the history of edits, so you can see what changed, when, and by whom, and you can coordinate multiple people working on the same project without overwriting each other. A key part of using it well is knowing the common workflows: cloning to get a copy of a repository, committing changes to capture a snapshot locally, pushing those commits to share with others, and pulling (or fetching) to incorporate others’ updates. Branching is essential too, because it lets you build features or experiments in isolation and then merge them back into the main line when ready. This combination—time-based history, collaboration, and the ability to organize work with clones, commits, pushes, pulls, and branches—captures what version control is all about. The other statements miss important aspects: it’s not just a backup tool with no collaboration benefits, it’s not a physical device, and it doesn’t automatically write code for you.
