How does the Enforce Referential Integrity option relate to the creation of orphan records?

What will be an ideal response?

Enforce Referential Integrity is a set of rules to help ensure that no orphan records are created in the database. An orphan record is a record in the "many" table that has no match in the "one" table. Checking the Enforce Referential Integrity option prevents this possibility for new records entered into the database.
