Answer is None. The question is kinda weird! Should it be, which one can be true?
1 cannot be true when x = 0.1, y =0.2, z=0.3
2. cannot be true when x=5, y=2, z=1
3. Works for numbers <0.1, -ve values of z and y. But if x =1, y =5 and z =4, it does not!
You should note that x CAN never be -ve! as x>y^2
By definition the min value of y^2 is 0, hence x>0!
