91876 x 2 is divisible by 8.
9 + 1 + 8 + 7 + 6 + x + 2 is divisible by 8.
33 + x is divisible by 8.
So smallest value of x = 7 is divisible by 8.
So the answer is none of above.

To substitute x=0, x=1, x=2, x=3....x=9.
When x=3 to substitute in between "6x2" is completely divisible by 8 and it's not given remaining value, if you have any doubt to substitute x=0 up-to 9 in between "6x2".
