Go with A.

(1) (y-2) = (x-1)
ie. y-x = 1

Sufficient

(2) y2 = (x + 1)2

ie. y = (x+1) or y= -(x+1)

Insufficient

If x ≠ 1, is y equal to x + 1?
(1) (y-2)/(x-1)=1
(2) y2 = (x + 1)2

Using (1)
y-2 = x-1
y=x+1
Sufficient

Using (2)
I assume this is actually y^2 = (x+1)^2
y = +/- (x+1)
Not sufficient

Hence A
