simplifying the equation we get the following :

(y-1)*(5-r) =0

If this is true then 3 things can be true :

1) y=1 OR
2) r=5 OR
3) y=1 and r=5

Now (A) and (B) doesn't provide any info from which y can be determined.

if r^2 =25, r can be +5 or -5. If r=-5, then y must be equal to 1 but we don't know that

if r=5, that mean (y-1) may or may not be =0

(E) is the answer
Drill baby drill !
