Press +1 Kudos, if you think my post gave u a tiny tip

Is 2x a multiple of y ? 2x + 2 is a multiple of y. - Insufficient. If y = 12 and x = 11, the 2x+2 is the multiple of y but 2x itself is not.

y is a multiple of x. - Insufficient y = 1, x = 1/2, Here y is multiple of x and 2x is a multiple of y. y = 1, x = 2, Here y is multiple of x but 2x is NOT a multiple of y.

1 is a multiple of every number. Also, 0 (ZERO) is NOT a multiple of any number.

sorry, i dont have this still in my head clearly.. so if anyone asks what are the multiples of 2

is the list 1,2,4,6,8,10,12 ... correct ?

Ok, looks like I completely messed up. My apologies.... It should be: y = 6, x = 2, Here y is multiple of x but 2x is NOT a multiple of y. So the answer is E.
