But if the parent key is deleted, wouldn't it make sense for the child keys to be set to a specified value?

I was going to choose C, but then I realized that would be the ON DELETE RESTRICT constraint, not NO ACTION. B makes the most sense here.

I think the correct answer is B. The question clearly states 'NO ACTION', which means no test is made for referential integrity when deleting the parent key.
