The correct option is B 2
We know the divisibility rule for 6:
If the number is exactly divisible by both 2 and 3 then the given number is also divisible by 6.
Here, 2+8+7+2=19
So, 19+2=21
Hence, 2874 is divisible by 6, because the last digit ends with even no. and the number is multiple of 3.
So, option B is correct.
