Assertion (A): In hydrodynamic journal bearings, the rotating journal is held in floating condition by the
hydrodynamic pressure developed in the lubricant.
Reason (R): Lubricant flows in a converging-diverging channel. [IES-1994]

(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
(d) A is false but R is true
