D) Sliding friction is weaker than static friction.

When your car slides on an icy road, it becomes hard to control primarily because the sliding friction (the force resisting the motion of the car tires sliding over the road surface) is weaker than static friction (the force that needs to be overcome to start moving an object at rest). Static friction helps keep the car tires gripped to the road, providing control. When sliding, this grip is significantly reduced, leading to less control.
