D. Neither

A only is correct.

Constant-velocity joints are able to transfer torque with zero angular velocity variation and near-zero vibration to the drive wheels at a constant rotational speed, while still accommodating the up-and-down movement of the suspension. In most cases, they are used in front wheel drive vehicles.
