Is it C? Statment one tells that two values are 1 and - 5 or -1 or 5 and statement 2 tells which one if greater. Taking any value of x as 1 or 5 we get one asnwer for x-y and that is 6

I guess it's A

We can change the needed value a little bit

X^2 + Y^2 - 2XY

From the first statement we can infer that the pairs of X and Y can be either (1,-5) or (-1,5).

Putting either of these pairs in the above value will give

1^2 + (-5)^2 - (-10) = 36

Or

(-1)^2 + 5^2 - (-10) = 36

So, A is sufficient.

Question is asking value of (x-y)^2 = x^2 + y^2 - 2xy
(1) Sufficient: xy = -5, Now, one has be positive and other negative. Possible values of x and y respectively are:
(1,-5), (-1,5), (5,-1), (-5,1).
=> x^2 + y^2 - 10. Now all the possible values of x and y will give same answer for x^2+y^2.
(2) Insufficient: No data about x and y is given.
