Hmm. You need to try all the choices one by one. Do you know how to calculate distances between two points?

C ;)

@Thebadyboy You're not suppose to give the answer all the time. You have to help her figure it out too.

Distance between two point is defined: $(x_{1}, y_{1}) and (x_{2}, y_{2})$ are points. $D = \sqrt{(y_{1} - y_{2})^2 + (x_{1} - x_{2})^2}$ is the distance
