If your Parent BU is set for "subscribers will be unsubscribed from all business units in the enterprise" then its setting will supersede the preference setting of any child BU under it.
If a BU is set as "Subscribers will be unsubscribed from this business unit only" and the customer unsubscribes from an email sent from that child BU, then they will be unsubscribed from that BU. They will remain subscribed in other business units
