FILL BLANK - Determine if the description is Master/Detail or Lookup: Up to 25 such relationships.
Lookup.
The question is asking you to determine whether the described relationship is a Master-Detail or Lookup relationship, based on the information provided.
However, the question is incomplete, as there is a blank space that needs to be filled in. Without knowing what information goes in the blank, it's difficult to determine the type of relationship being described.
Master-Detail and Lookup relationships are two types of relationships that can be created between objects in Salesforce.
In a Master-Detail relationship, the child record is dependent on the master record. The child record cannot exist without a master record, and if the master record is deleted, the child record will be deleted as well. Master-Detail relationships are typically used when there is a one-to-many relationship between two objects, and the child object is always associated with a single master object.
In a Lookup relationship, the child record is not dependent on the master record. The child record can exist without a master record, and if the master record is deleted, the child record will still exist. Lookup relationships are typically used when there is a one-to-many or many-to-many relationship between two objects, and the child object may be associated with multiple master objects.
In terms of the number of relationships that can be created, there is a limit of 2 Master-Detail relationships per object, but there is no limit to the number of Lookup relationships that can be created.
In summary, to determine whether the described relationship is a Master-Detail or Lookup relationship, we need more information. The number of relationships alone is not enough to make this determination.
