(1) y ≠ 1
(2) x + 2 is a multiple of y

1)insuf - it means y>1
2) x + 2 is a multiple of y

(x+2) = Y*INTEGER

from the stem we know that X=Y*INTEGER

if we combine these two statements:

Y*INTEGER+2=Y*INTEGER

Y( Integer - INTEGER) = 2

we can get 2 in two ways : 2x1 or 1x2

INSUF - we dont know which one is 2

1+2 ) SUFF

we know y is not equal to 1 from first statement

Hence, C

Am I right ?

Thanks. You are correct.
