In Git, if a branch does not exist and you need to create and switch to it in one command, use:
git checkout -b <branch_name>
OR
git switch -c <branch_name>
(For newer Git versions, switch is preferred.)
* git checkout -b staging
* -b creates a new branch.
* staging is the new branch name.
* This also switches to the new branch immediately.
* Why the other options are incorrect?
* A. git branch -m st # Incorrect, -m is used for renaming a branch, not creating one.
* B. git commit -m staging # Incorrect, commit -m is used to commit changes with a message, not to create a branch.
* C. git status -b staging # Incorrect, git status shows the current repository state, but -b is not a valid option for it.
