The answer to this question is c
If she takes 60 then her sister takes 24
In order for it to be a square, we see that it has to have a distance of 3 from the points B and C, since the distance between A and B is 3. A square is a parallelogram, so AD needs to be parallel to BC. Hence, since the vector BC is (0,3), we have that the vector AD is also (0,3). So, adding the coordinates of the vector to A, we get that D=(0,3).
