I strongly support the Correct. Sets contain tuples (rows). Sets do not contain 'pages' of tuples!! Set based = tuple based = row based. If you involve pages you involve the physical database design, some the relational model is trying to abstract away. Otherwise we'd all still be handling disk sectors and pointers from one disk structure to another...
