An unpolarized light of intensity

32 \mathrm{~W} / \mathrm{m}^2

passes through three polarizers, such that the transmission axis of last polarizer is crossed with that of the first. If the intensity of emergent light is

3 \mathrm{~W} / \mathrm{m}^2

, then the angle between the transmission axes of the first two polarizers is

Options

A $30^{{}^{{}^{\circ}}}$
B $19^{{}^{{}^{\circ}}}$
C $45^{{}^{{}^{\circ}}}$
D $90^{{}^{{}^{\circ}}}$

Correct answer
