Quizplus · Accepted Answer

Referential integrity constraints are primarily used to enforce the relationships between tables, specifically between primary keys and foreign keys. Foreign keys are used to reference values in other tables, and referential integrity constraints ensure that these references are valid by limiting the possible values that can be entered into a foreign key column. Therefore, the correct answer is C, foreign key.
