In a cylindrical region uniform magnetic field which is perpendicular to the plane of the figure is in increasing with time and a conducting rod `PQ` is placed in the region.If `C` is the centre of the circle then

A

`P` will be at higher potential than `Q`.

B

`Q` will be at higher potential than `P`.

C

Both `P` and `Q` will be equipotental.

D

no `emf` will be developed across rod as it is not crossing /cutting any line of force.
