The correct option is Microsoft Entra ID.

GitHub Enterprise Cloud supports team synchronization with Microsoft Entra ID so you can map identity provider groups to GitHub teams and keep membership in sync automatically. When group membership changes in Entra ID the corresponding team membership in GitHub updates without manual maintenance. This is the only identity provider that integrates with this feature for organizations on Enterprise Cloud.

The option PingOne is not supported for GitHub team synchronization on Enterprise Cloud and it cannot mirror identity provider groups to teams.

The option Okta can provide single sign on and user provisioning for GitHub but team synchronization is not available with this provider on Enterprise Cloud.

The option Google Cloud Identity does not integrate with GitHub team synchronization and it cannot automatically map groups to teams.
