A monochromatic source of light is kept at a distance of 0.2 m from a photoelectric cell. Stopping potential `V_(0)` and saturation current `I_(0)` are 0.6 V and 18.0 mA, respectively. Now the source is kept at a distance of 0.6 m from the cell. Then

A

`V_(0) = 0.2V, I_(0) = 18.0 mA`

B

`V_(0) = 0.2 V, I_(0) = 2.0 mA`

C

`V_(0) = 0.6V, I_(0) = 18.0 mA`

D

`V_(0) = 0.6V, I_(0) = 2.0 mA`
