A number that is divisible by 12 is also divisible by 3 and 4 (or twice by 2). Then, we can check which of the choices is the right one without the need of the calculator.

If we check which choices are divisible by 3, summing the digits of the number we need to get a multiple of 3, thus we can get rid of all the choices but B and C.

Then, among the two, the one that is also divisible by 2 is C.

Answer C
