What command would be used to delete a branch locally?

The command used to delete a branch locally is "git branch -d branch_name." This command effectively removes the specified branch from your local repository. The "-d" flag stands for "delete," and it will also ensure that the branch being deleted has been fully merged into its upstream branch, providing a safeguard against accidental loss of unmerged work. If you try to delete a branch that hasn't been merged, the command will issue a warning and prevent the deletion, which is useful for protecting your work.

The other commands mentioned would not achieve the intended effect. For instance, "git remove branch_name" and "git delete branch_name" are not valid Git commands, as they do not align with the syntax and structure of Git's command set. Additionally, "git rm branch_name" is a command meant for removing files from the staging area or the working directory, not for deleting branches. Thus, using "git branch -d branch_name" is the correct approach to removing a branch locally in Git.
