Which statement about the Lookup Relationship between a Custom Object and a Standard Object is correct?

1. The Lookup Relationship on the Custom Object can prevent deletion of the Standard Object.

2. The Lookup Relationship cannot be marked as required on the page layout for the Custom Object.

3. The Custom Object will be deleted when the referenced Standard Object is deleted.

4. The Custom Object inherits security from the referenced Standard Objects.

The correct answer is: The Lookup Relationship on the Custom Object can prevent deletion of the Standard Object.

In a Lookup Relationship, a Custom Object can indeed be configured to establish a relationship with a Standard Object. In this case, if you select the option that states the Lookup Relationship can prevent the deletion of the Standard Object, you are highlighting the "parent-child" behavior that can be managed in a Lookup Relationship—specifically through the use of the 'Restrict Delete' option available in the setup. When this option is enabled in a Lookup Relationship, it means that if there are any related records in the Custom Object, Salesforce will not allow the deletion of the Standard Object. This is particularly useful for maintaining data integrity and preventing orphaned records in the Custom Object. This functionality is an important aspect of designing relationships between objects in Salesforce, ensuring that data remains consistent and that dependencies are respected when modifications are made to records. Thus, this capability makes the first statement accurate concerning the behavior of Lookup Relationships. Other options do not encompass these aspects of Lookup Relationships correctly, as they either misunderstand the requirements around required fields or the consequences around deletion.
