Because there is friction, the force of static friction acts

hey...
answer is Both.
Static friction - The Friction that exists between a stationary object and the surface on which it's resting. A frictional force occurs when you try to push an object alongside a surface. Once the objects have already started moving, kinetic friction takes over
Rolling friction - The friction that exists between the rolling surface and the surface on which it is rolling.
hence both friction is necessary, thanks....
