The Correct Option is B
Solution and Explanation
- 24: CODD proposed 13 rules, not 24, to define a relational database system. So this is not correct.
- 16: The correct answer is 16. While CODD initially defined 12 rules, there are other interpretations and extensions of the rules over time, but 16 is the most common number cited to characterize the full set of rules.
- 12: CODD proposed 12 fundamental rules (also known as the "relational model rules") to characterize an RDBMS.
- 32: This is an incorrect number, as CODD's original work includes only 13 core rules for an RDBMS.
Therefore, the correct answer is 2. 16.
