An unpolarized beam of light is incident on a group of three polarizing sheets which are arranged in such a way that plane of rotation of one make an angle of \( 60^{\circ} \) with the adjacent one. The percentage of incident light transmitted by first polarizer will be
(a) \( 6.25 \% \)
(b) \( 12.5 \% \)
(c) \( 50 \% \)
(d) None of these
