Answer / guest
Answer: B
Referential integrity controls prevent the occurrence of
unmatched foreign key values. Given that a nonexistent
employee does not appear in the employees' table, it will
never have a corresponding entry in the salary payments
table. The other choices cannot be detected by referential
integrity controls.
