Which capabilities are typical of version control systems used for collaboration in software development?

• A. Track changes, enable branching/merging, and preserve history to prevent conflicts and enable rollbacks.
• B. Store only the latest version of each file.
• C. Prevent collaboration by locking files.
• D. Automatically generate documentation.

Answer: (A)

Version control systems in software development help teams work together by managing how code changes over time. The essential capabilities are tracking every change to files, which records who made what change and when; enabling branching and merging so different features or fixes can be developed in isolation and later combined; and preserving a complete history so you can review, compare, revert, or roll back to previous states if needed. This history also supports understanding how the project evolved and who contributed what.

Storing only the latest version misses all the past changes, which is crucial for debugging and auditing. Locking files to prevent collaboration goes against the collaborative workflow that modern VCSs support, where concurrent work is common and conflicts are resolved through merging. Automatically generating documentation is helpful, but it is not a core function of version control itself. The combination of tracking changes, enabling branching/merging, and preserving history best supports collaboration in software development.
