D Correct answer
Explanation

If Jill is 12, Bill is $12+4=16$. David is $16+2=18$. The question asks for the percent Jill is older than David, but Jill (12) is younger than David (18). The options provided are ratios, not percentages, making the question and options nonsensical. 'None of the above' is the only logical choice.
