Correct Answer - Option 2 : (A) and (B) only
In questions like this, always follow logical deduction and always go by the options.
In statement (A), substituting both the values, we find that they satisfy the equation.
∴ Option (3) can be neglected.
In statement (B), solving the equations, we find out that the roots are equal to -1/3.
In statement (C) after putting 27/256 in place of K, we find out that one of the roots is equal to 0.71(approx) whereas the other is about 0.03(approx) which does not satisfy the criteria.
Always try to solve them by the options provided.
