A current `I` is passing through a wire having two sections `P` and `O` of uniform diameters `d` and `d//2` respectively. If the mean drift velocity of electrons in section `P` and `Q` is denoted by `v_(P)` and `v_(Q)` respectively, then

A

`v_(P) = v_(Q)`

B

`v_(P) = 1/2v_(Q)`

C

`v_(p) = (1/4)v_(Q)`

D

`v_(P) = 2v_(Q)`
