A polarized light is incident on a polaroid. Let $$I_0$$ be the intensity of light transmitted by this polaroid. Now, a very large number (say N) of polaroids is placed in a row with their axes displaced through a small angle $$\theta$$ successively. If the last polaroid is crossed to the first one, the intensity of light transmitted by the last polaroid is about

A

zero

B

$$\frac{I_0}{2}$$

C

$$I_0$$

D

$$\frac{I_0}{N}$$
