For a particular orientation there shall be darkness as observer sees through the polaroid

B

the intensity of light as seen through the polaroid shall be independent of the rotation

C

the intensity of light as seen through the polaroid shall go through a minimum but not zero for two orientations of the polaroid

D

the intensity of light as seen through the polaroid shall go through a minimum for four orientations of the polaroid
