What does a Git Commit do?

A Git commit captures the current state of the project's files, effectively saving the changes made since the last commit. When you execute a commit, it creates a snapshot of your files at that specific point in time and includes a message that helps describe those changes. This allows you to retain a history of the project's development that is crucial for version control, enabling you to go back to any previous state of the project. By adding the changes to the repository, you ensure that your work is recorded and can be shared with others when pushing to a remote repository.

The other choices do not accurately describe the primary function of a commit. For instance, removing files from the repository is not its purpose; instead, files can be staged for removal before committing. Fetching changes from a remote repository involves syncing with other contributors' changes but is a separate action from committing. Lastly, creating a new branch is related to organizing different lines of development and does not pertain to committing changes within the existing branch.
