Light from sodium lamp is made to pass through two polaroids placed one after the other in the path of light. Taking the intensity of the incident light as `100%`, the intensity of the out coming light that can be varied in the range

`0% " to "100 %`

`0% " to "50 %`

`0% " to "25 %`

`0% " to "75 %`
