The correct option is group because it creates a collapsible log section with a clear title in GitHub Actions.

This command lets you start a titled section in the job log and then close it with a matching end command. Everything emitted between the start and end is grouped under that title which makes long logs much easier to navigate and keeps related messages together.

The echo option only prints text to standard output and does not create collapsible sections by itself. In practice you often use echo to emit workflow commands, yet the command that enables grouping is group rather than echo.

The add-mask option is used to hide sensitive values in logs and it does not organize output into collapsible groups.

The stop-commands option temporarily disables and later re enables workflow command processing and it does not create titled or collapsible sections in logs.
