The correct options are The name in the action metadata must be unique across GitHub Marketplace, The action's metadata file named action.yml is located at the root of the repository, The repository that hosts the action is public, The listing name cannot match any existing GitHub Marketplace category, and You have accepted the terms of service for publishing actions in GitHub Marketplace.

GitHub uses the information in an action's metadata to create its Marketplace listing and to prevent conflicts. This is why the name in the action metadata must be unique and why the listing name cannot match any existing GitHub Marketplace category. When naming requirements are satisfied the automated Marketplace checks can pass and the action can go live without manual review.

Automatic validation also confirms the repository structure and visibility. The action's metadata file named action.yml is located at the root of the repository so GitHub can detect and parse it correctly, and The repository that hosts the action is public so the listing can be discovered and used by the community. These requirements enable immediate publication once all checks succeed.

Marketplace publication also requires agreement to the platform terms, so You have accepted the terms of service for publishing actions in GitHub Marketplace must be completed. After acceptance the listing can publish right away when the other conditions are met.

You must enable Cloud Build in your Google Cloud project before publishing is incorrect because it is unrelated to GitHub Actions and GitHub Marketplace and plays no role in listing an action.
