In order to find this out, you could convert all the numbers to have the same common denominator. If you made the denominator 18, then 8/9 = 16/18 1/2 = 9/18 1 = 18/18 0 = 0/18.
This allows a clear comparison which shows that 8/9 is closest to 1 out of those options as it is only 2/18 (or 1/9) different. Therefore, the answer is B.
