A motorcycle travels 8.9 meters per second around a track. The dotted line shows the path of the motorcycle. The arrow shows the direction of the motorcycle at position 1.

Which comparison of the motorcycle's motion is correct?

A. At positions 1 and 3, the velocities are the same, but the accelerations are different.
B. At positions 1 and 4, the speeds are the same, but the velocities are different.
C. At positions 2 and 3, the accelerations are the same, but the velocities are different.
D. At positions 2 and 4, the velocities are the same, but the speeds are different.​
