Northern Trail Outfitters has two custom objects that are part of a master- Detail relationship.

The correct answer is D. The Owner field on the Master record.

In a master-detail relationship, the detail record does not have independent ownership. Salesforce documentation states that the Owner field on the detail object isn’t available and is automatically set to the owner of the related master record.

Sharing is also controlled by the parent/master record. Salesforce Help explains that when a custom object is on the detail side of a master-detail relationship, its organization-wide default is set to Controlled by Parent.

A and C are incorrect because the detail record does not maintain independent ownership in a master-detail relationship. B is incorrect because ownership is not determined by a default owner setting on the parent object; it comes from the actual Owner field on the master record.
