FILL BLANK - Determine if the description is Master/Detail or Lookup: Child is deleted when parent is deleted.
Master/Detail.
This description refers to a Master-Detail relationship between the Parent object and Child object. In a Master-Detail relationship, the Child object is dependent on the Parent object, meaning that the Child object record cannot exist without a corresponding Parent object record.
When a Master-Detail relationship is created, the administrator has the option to specify the 'Delete' behavior. In this case, the behavior is set to 'Cascade Delete', which means that if the Parent record is deleted, all the related Child records will also be deleted automatically.
On the other hand, in a Lookup relationship, deleting the Parent record would not delete the related Child records automatically, as the Child object is not dependent on the Parent object. In a Lookup relationship, the Child record can exist even if the Parent record is deleted.
So, in summary, if the description states that a Child record is deleted when the Parent record is deleted, it indicates a Master-Detail relationship with Cascade Delete behavior.
