Cancel Apple One free trial

I had existing current subscriptions to Apple Music and iCloud+ when I signed up for the Apple One free trial a couple of days ago. Both previous Music and iCloud subscriptions had time left before they would have been due for renewal.

If I cancel Apple One without opting to keep any individual services, will Music and iCloud+ revert to the previous subscriptions?

Or do I need to opt to keep the Apple One iCloud+ subscription?

Thanks.
