What is the Git command to create and switch to a new branch named 'feature' in one step?

• A. git checkout -b feature
• B. git switch feature
• C. git branch feature
• D. git merge feature

Answer: (A)

Creating and switching to a new branch in one step is done by instructing Git to both make the branch and check it out immediately. The -b option with the checkout command does exactly that: it creates a new branch named feature from the current commit and immediately switches your working directory to that branch. This is why it’s the best choice for a single-step creation and switch. The other commands don’t achieve both actions in one go: switching to a branch requires that branch to already exist, so the switch command would fail if feature isn’t there; creating a branch without switching leaves you on the current branch; and merging combines histories rather than creating or switching branches. If you’re using a newer Git, you could also use switch -c feature to create and switch, but the given one-step option is the checkout -b feature form.
