A Question is given followed by two Statements I and II.

- AThe Question can be answered by using one of the Statements alone, but cannot be answered using the other Statement alone
- BThe Question can be answered by using either Statement alone
- CThe Question can be answered by using both the Statements together, but cannot be answered using either Statement alone
- DThe Question can be answered even without using any of the Statements
Explanation
N*M=252=12*21 (M the digit-reverse of N). Statement I (N+M=33) leaves {12,21} unordered - insufficient alone. Statement II (N>M) pins N=21 alone. So one statement alone suffices, the other does not. Assuming Statement I fixes N is the error.
