The following correctly explains the shining of light through a cellophane except:
a. As white light passes through red cellophane, the cellophane absorbs all colors except red.
b. Green light can’t easily pass through green cellophane because it shows the same color.
c. A red light passing through red cellophane will simply go through since they have the same color.
d. Red light can’t easily pass through green cellophane since the collophane absorbs the red light.
