Unpolarized light is passed through polarizer 1.The light then goes though polarizer 2 with its plane of polarization at 45.0 $\degree$ to that of polarizer 1.Polarizer 3 is placed after polarizer 2.Polarizer 3 has its plane of polarization at 45 $\degree$ to the plane of polarization of polarizer 2 and at 90 $\degree$ to that of polarizer 1.What fraction of the intensity of the original light gets though the last polarizer?
A)0.707
B)0.500
C)0.250
D)0.125
