The correct option is A failed workflow run is created for every subsequent commit.

Each push to the default branch triggers the workflow, and GitHub validates the workflow file before running any jobs. When the YAML is malformed, GitHub still creates a run for the triggering event and immediately marks it as failed due to the configuration error. This repeats after every new commit until the YAML is fixed.

Cloud Build is unrelated to GitHub Actions and does not control workflow behavior in a GitHub repository.

GitHub automatically repairs the invalid YAML in the workflow file is incorrect because GitHub does not modify your repository contents and it only reports validation errors.

GitHub Actions is turned off for the repository until the YAML is fixed is incorrect because Actions remains enabled and other valid workflows continue to run, while the invalid one produces failed runs on each triggering event.
