Which type of friction is associated with rolling motion between a ball and a surface?

Explanation:
Rolling friction is the resistive force that acts when a ball rolls across a surface. As the ball contacts and deforms the surface (and the surface deforms back), energy is dissipated and a small opposing torque arises, slowing the roll. This type of friction is specifically the friction associated with rolling motion, distinct from kinetic friction (sliding) and static friction (which prevents slipping to allow rolling). Magnetic friction isn’t involved here. So the friction that accompanies rolling motion is rolling friction.
