Which statement is true about Master-Detail relationships in Salesforce?

1. Child records can exist without a parent record.

2. Record deletion does not affect related child records.

3. Security settings are independent of parent records.

4. Roll-up summary fields can be created on the parent record.

The correct answer is: Roll-up summary fields can be created on the parent record.

The statement about Master-Detail relationships indicating that roll-up summary fields can be created on the parent record is correct because this is a fundamental feature of such relationships in Salesforce. A Master-Detail relationship establishes a strong connection between two objects, where the detail (or child) record is closely tied to the master (or parent) record. In this setup, a roll-up summary field allows you to perform calculations on the related child records and display the results on the parent record. This feature is particularly useful for aggregating data, such as counting the number of child records, summing a field value from those child records, or even getting the minimum or maximum values. This capability is unique to Master-Detail relationships and showcases the dependency and close association between the parent and child records. In contrast, if child records could exist independently of their parent records, if deletion of a parent record did not cascade to the child records, or if security settings were treated independently, the traditional characteristics of a Master-Detail relationship would not be preserved. Therefore, the ability to create roll-up summary fields on the parent record highlights the integral connection of the Master-Detail relationship and its features, reinforcing the correctness of the statement.
