I keep getting the wrong answers on a few problems I am working on. Could anybody tell me how do get the answers from these motion graphs please? Thank you! (They are attached)

The question is as follows for motion_diagram1.jpg

The figure below shows 3 motion diagrams A, B, and C. The time intervals are the same in all 3 cases, and the objects move from right to left. You have to rank the 3 cases in decreasing order of the velocities. Which ranking is correct?

a. A > B > C
b. A > C > B
c. B > C > A
d. C > B > A
e. C > A > B
