FILL BLANK - Determine if the description is Master/Detail or Lookup: No inherited sharing:
Lookup.
The question is asking whether a relationship between two objects in Salesforce is a Master/Detail or Lookup relationship when there is "no inherited sharing."
Master/Detail and Lookup are two types of relationships that can be defined between two objects in Salesforce.
In a Master/Detail relationship, the child object is dependent on the master object and inherits its sharing settings. When the master object's record is deleted, all related child records are also deleted. The security and sharing of the child records are controlled by the master record.
In a Lookup relationship, the child object has a lookup field that references the parent object. The child object does not inherit sharing settings from the parent object, and the parent record can be deleted without affecting the child records.
The phrase "no inherited sharing" means that the child object in the relationship does not inherit the sharing settings from the parent object. This means that the relationship is a Lookup relationship, as Master/Detail relationships always inherit sharing settings.
Therefore, the answer to the question is Lookup.
