When is the Master branch typically updated?

The Master branch is typically updated when the production system is updated. This reflects a common practice in version control and software development to ensure that the code in the Master branch is stable and reflects what is currently deployed in production. Updating the Master branch at this point ensures that it contains the latest and most reliable codebase, which is essential for maintaining continuity and preventing discrepancies between development and production environments.

In many development workflows, particularly those that use Git, the Master branch serves as the main line of development and is ideally kept in a state that is deployable at all times. When changes are finalized and ready to be pushed to production, reflecting those changes in the Master branch helps maintain a clear, organized record of what code is currently in use.

While other options may involve activities related to branches, they do not inherently reflect the overarching principle of keeping the Master branch aligned with the live production system, which is a critical aspect of effective version control practices.
