The cathode of a photoelectric cell is changed such that the work function changes from `(W_(1) to W_(2) (W_(2) gt W_(1))`. If the current before and after change are `I_(1)` and `I_(2)`, all other conditions remaining unchanged , then (assuming `hv gt W_(2)`)

A

`I_1=I_2`

B

`I_1 lt I_2`

C

`I_1gt I_2`

D

`I_1 lt I_2 lt 2I_1`
