Try options using distance formula between two coordinates. \sqrt{(x2-x1)^2 + (y2-y1)^2}
A. (0,0) & (4,7) The distance is \sqrt{65}
B. (0,0) & (4,10) The distance is \sqrt{116}
C. (0,0) & (5,6) The distance is \sqrt{61}
D. (0,0) & (6,2) The distance is \sqrt{40}
So it's D
A. (0,0) & (4,7) The distance is \sqrt{65}
B. (0,0) & (4,10) The distance is \sqrt{116}
C. (0,0) & (5,6) The distance is \sqrt{61}
D. (0,0) & (6,2) The distance is \sqrt{40}
So it's D
