   A CI job needs to push an image to the GitLab Container Registry, but the job runs on a shared runner that does not have Docker installed. The team decides to use the Docker-in-Docker (dind) service. What is the correct way to authenticate to the registry in this job?

   • AUse the docker login command with the CI_JOB_TOKEN as the password, but only if the job is running on a protected branch.
   • BAdd a before_script that runs docker login with $CI_REGISTRY_USER and $CI_REGISTRY_PASSWORD.
   • CUse the image: keyword to specify the image to push, and GitLab will automatically authenticate.
   • DSet the CI_REGISTRY_USER and CI_REGISTRY_PASSWORD as environment variables in the job, and GitLab will automatically push the image.
