The answer is C.
The % operator gives you the remainder when you divide one number by the other. Since num can only be an integer, the next highest remainder after 9 would be 10. You can't have a remainder of 10 if you're dividing by 10, because 10 would just go into the dividend one more time. In other words, 19 divided by ten is one with a remainder of 9, but 20 divided by 10 isn't one with a remainder of 10, it's just two.

D. 10 is not equal to 0.
