You try; that's rather the point.
PS On second thoughts, I think it's an unfair test. In 2, it only works if you make 'I'm' into one syllable. And 9 only works if you make 'You're' into one syllable; and then it's either B or C, depending on how you count syllables in 'really'. The others are straightforward. (Hint: Count the syllables. That should get you started.)
