The condition of y=x^2 along with x=y is true only for two values of x i.e. 1 and 0 and NOT for -1. Since statement 2 already says x=0 the only applicable value left for x is 1 -> y=x^2=1. Hence, both statements taken together gives us an exact solution. IMO the answer is C.
Please correct me if I am wrong.

(S1) say y=x^2 => y = X * X
so if X = 4 ; Y is 16 , if X=3 ; Y=9 ........
I think you have missed the negative scenario.

Hi 2011mbaaspirant, why do you say that -1 cannot be an answer?
Suppose case a
x=-1
y=1
from statement 1)
Y = X ^ 2 => 1 = (-1)^2

case 2
x=1
y=1
from statement 1)
Y = X ^ 2 => 1 = (1)^2

in both x is not equal to 0
so x can be 1 or -1

please correct me if I am wrong.
thanks!
