Solution

The correct option is B Rolling friction is less than sliding friction.
Rolling friction is the resistance to motion experienced by a body when it rolls on another surface. It is much lesser than sliding friction for the same pair of bodies. Thus, when ball bearings are used in between two machine surfaces, sliding friction between them will be replaced by rolling friction.
