Rolling friction is defined as?

Explanation:
Rolling friction is the resistance that opposes motion when a wheel or ball rolls over a surface. It comes from the grip and tiny deformations at the contact patch between the rolling object and the surface. As the wheel rolls, the surface must grip the wheel and then recover its shape, dissipating energy in the process. This grip-like interaction at the contact area is what slows the rolling motion. The other options describe friction in different contexts (sliding, air resistance, magnetic effects) and do not capture the contact/grip interaction characteristic of rolling motion.
