Show answer & explanation
Correct answer: C
The correct answer is 12. In DBMS/RDBMS exams, the standard term is Codd's 12 Rules, which refers to the core rules numbered Rule 1 through Rule 12. Rule 0 is the foundational rule. If Rule 0 is counted separately along with Rules 1 to 12, the total rule statements become 13. However, this question asks for the commonly referred core Codd's rules excluding Rule 0, so the answer is 12.
