The correct option is Hosting and sharing reusable actions with the broader community.

GitHub Marketplace exists to let maintainers and vendors publish Actions that others can discover, install, and reuse across their workflows. It provides versioned releases, examples, and search so teams can adopt proven automation components rather than building everything from scratch.

Managing and designing the overall workflow structure is not what the Marketplace does. Workflow structure is defined in YAML files in the repository and is managed in the Actions configuration rather than through the Marketplace catalog.

Monitoring live progress and metrics for individual jobs and runs is handled in the Actions run views and logs within the repository and not in the Marketplace which is a discovery and distribution hub.

Cloud Build refers to a separate build service that is not part of GitHub Actions or the GitHub Marketplace and therefore it does not describe the Marketplace function.
