The correct option is Open the workflow run in GitHub Actions and expand the container action step to view the step logs.

GitHub Actions captures the standard output and error streams from each step of a workflow, including Docker container actions, and presents them in the workflow run logs. Opening the run and expanding the job and then the specific step lets you see the container action’s detailed output, timestamps, and the nonzero exit code that explains the failure. You can also download the logs and, if needed, enable additional verbosity with the ACTIONS_STEP_DEBUG and ACTIONS_RUNNER_DEBUG secrets for deeper troubleshooting.

The option Use git log to review repository commit history for the workflow is incorrect because git log shows commit history rather than runtime execution logs from GitHub Actions steps or container actions.

The option View the build logs in Cloud Build in the Google Cloud console is incorrect because the container action runs on a GitHub Actions runner and its logs are stored with the GitHub workflow run rather than in Google Cloud Build.

The option Run docker logs on the runner to read the container output is incorrect because you do not have shell access to GitHub hosted runners and even with a self hosted runner the supported and centralized place to view step output is the workflow step logs in the Actions run.
