Option 3 : Sliding to rolling

Rolling friction is the resistive force when a body rolls on a surface.
On the other hand, sliding friction is the resistive force when a body slides on a surface.
The force of friction depends on the area of contact between the surfaces.
As the area of contact is less in the case of rolling than in the case of sliding, the friction reduces in the former case.
