Hmm, this one's tricky. I think the answer is C) Referential integrity, since the HOUSING relation has a foreign key that references the STUDENT relation, but the ON DELETE constraint is set to NO CHECK, which could lead to dangling references.

I believe the correct answer is C) Referential integrity because the foreign key reference is not properly set up.

I agree with Catarina, the foreign key constraint is not properly defined.
