To create a new feature in a separate branch and check out the new version, the correct commands are needed.
Option B provides the correct sequence of Git commands to achieve this task. The command git checkout -b feature creates a new branch named "feature" and switches to it immediately, which is exactly what is required when starting development on a new feature while keeping the production release intact in the "master" branch.
