D 8m
E none of the above​

Answer 1

The answer is this

So basically you have to find the HCF of the three numbers.
As we have options here we can see that one of the numbers is odd. So we can rule out 12 and 8. That leaves 9 and 7. As we can see all the numbers are divisible by nine. Therefore, our answer is 9.
