Assertion (A): Hydrostatic lubrication is more advantageous when compared to hydrodynamic lubrication during
starting and stopping the journal in its bearing.
Reason (R): In hydrodynamic lubrication, the fluid film pressure is generated by the rotation of the journal. [IES-1998]

(b) Both A and R are individually true but R is not the correct explanation of A
(c) A is true but R is false
