Yes the answer should be c..as 1 and 2 alone are not sufficient...to solve it would be like y^3=27..so y =3

(1) This statement narrows the value of y to {1, 3, 9, 27} but obviously not a single value like we're looking for so its insufficient.

(2) x = y^2. The most tempting thing about this one is if you let knowledge and information from (1) bleed onto it. This actually doesn't limit y to anything other than y^2 being an integer or, rather, that y is the square root of x.

Combining the two, however gets us there because (1) limits our choices to {1, 3, 9, 27} and (2) limits our possibilities to perfect square roots. In that set of available choices, only 3 is the square root of another factor of 27.
