Your data gives a parabola with equation $y=\frac{-x^{2}}{4}+27$

It's a multiple choice question, sport, so you get the answer any which way you can (even if that means getting rid of all the wrong ones so that last man standing has to be the correct one) - that's just the nature of multiple choice testing.
