What does version control primarily help with in software development?

Version control primarily helps with recording changes to files over time, which is a crucial aspect of software development. By keeping track of each modification made to the codebase, version control systems enable developers to understand the history of changes, revert to previous versions if necessary, and collaborate more effectively with team members. This detailed tracking allows for easier debugging, as developers can pinpoint when an error was introduced, and it helps in managing concurrent work by multiple developers, preventing conflicts that can arise when merging changes.

The other choices do not align with the primary function of version control. For example, managing software licenses pertains to legal and administrative tasks that are outside the scope of version control systems. Creating user interfaces is a design and implementation task that involves user experience considerations rather than managing code revisions. Training machine learning models involves algorithms and data processing, which is a distinct domain in software development and does not relate to tracking changes in code or files. Hence, the correct answer highlights the core purpose of version control in a development environment.
