Explanation

Default environment variables The default environment variables that GitHub sets are available to every step in a workflow. Because default environment variables are set by GitHub and not defined in a workflow, they are not accessible through the env context [Not B]. However, most of the default variables have a corresponding, and similarly named, context property. For example, the value of the GITHUB_REF variable can be read during workflow processing using the ${{ github.ref }} context https://docs.github.com/en/actions/reference/workflows-and-actions/variables
