Answer

Choice B.

Work Step by Step

The rider would rotate half the angle in half the time ONLY if the object were spinning at constant angular speed. However, it is accelerating with constant angular acceleration, so starting from rest it will rotate an angle proportional to the square of the time. In half the time, it would only have rotated a fourth of the angle.
