What is a key feature of a Master-Detail relationship?

1. It allows sharing of parent record ownership

2. It enables creation of complex hierarchy structures

3. It provides more access control than Lookup relationships

4. It requires that child records depend on parent records

The correct answer is: It requires that child records depend on parent records

A Master-Detail relationship is characterized by a dependency where child records are inherently linked to parent records. This means that if a parent record is deleted, all associated child records will also be deleted, which emphasizes the strong dependency of child records on their parent. In a Master-Detail relationship, the child records cannot exist without the parent records; they are crucial for defining the relationship between the two objects. Additionally, the ownership and sharing settings of child records are automatically inherited from the parent record, further reinforcing the dependency. This relationship type supports the creation of summarized fields on the parent object, allowing for aggregate calculations from child records, showing the relationship's structural and functional characteristics. The other options do not capture the essential definition and behavior of a Master-Detail relationship as accurately as the requirement for the child records to depend on the parent.
