When creating a master-detail relationship, what is required for standard objects?

1. Standard objects can never be on the detail side.

2. Standard objects can only be detail objects.

3. Custom fields are required on standard objects.

4. Standard objects have fewer rules than custom objects.

The correct answer is: Standard objects can never be on the detail side.

When creating a master-detail relationship in Salesforce, the detail side of the relationship must be a custom object; therefore, standard objects cannot be positioned as detail objects. This is fundamental to maintaining data integrity and ensuring that standard objects only serve as parent objects in this type of relationship. Master-detail relationships inherently create a strong ownership and cascade delete behavior, which is something that Salesforce manages specifically with custom objects as details. The restrictions around standard objects are designed to preserve the core functionality of these objects while allowing businesses to leverage the flexibility of custom objects. Hence, the assertion that standard objects can never be on the detail side accurately reflects the rules governing these relationships. Understanding this limitation helps users design data models correctly in Salesforce, ensuring that the relationships between objects align with the platform's structural requirements.
