(1) r2 = 25
(2) r = 5

(y+3)(y-1) – (y-2)(y-1) ==>(y-1)((y+3)-(y-2))==>(y-1)(y+3-y+2)
(y-1)5=r(y-1)

Hence Both A and B alone are suff.

Hence D

Seems to be a weird Q. Source Please?

You can actually derive r=5 from the given eq

2 does not add any thing

1 gives 2 more r values

Together also does not help. Hence E
