What primary purpose does a Git repository serve?

A Git repository primarily serves as a central location where the entire history of a project's files is managed. This encompasses file versions, branches, and commits. The aspect of versioning is crucial, as it allows developers to track the evolution of their code over time, see changes made by different contributors, revert to previous versions if needed, and manage multiple lines of development through branches.

Understanding the role of branches is also key; they enable parallel development workflows, allowing teams to work on features or fixes independently before merging back into the main project. This collaborative approach is fundamental to modern software development practices and is a core advantage of using Git.

Other options presented do not align with the primary functionality of a Git repository, making them less relevant in the context of version control and collaborative development.
