    Statement II alone is sufficient.
  3. C
    Statement I alone is sufficient.
  4. D
    Both Statement I and Statement II together are sufficient.

Solution & Step-by-step Explanation

We have variables (). To find unique values for variables, we require at least independent equations. Statement I gives equation, and Statement II gives another. Combining them gives only equations:


We still cannot find unique values for and . Hence, both statements together are not sufficient.
