Uncertain about how to approach this question. Using SI units I eliminated B. Any help would be appreciated. Thanks :D

Note that this is a multiple choice question.
You don't have to find the answer, you only have to find which one of these answers is the answer.

Your experience should tell you that an object falling on Earth [approximating g = 10] will fall to 5m in one second and to 20m in 2 seconds - an extra 15m.

This if a = 10, x = 5 and h = 15 then t1 = 1 and t2 = 2.

Substitute those values in and only one of the options will yield the correct answer.

I repeat - to emphasise:

This is a multiple choice question.
You don't have to find the answer, you only have to identify which one of the offered answers is the correct.

Alternately you can work with the equation you identified and derive the solution.
