A Beam of Unpolarized Light with an Intensity of 1000 $\theta$

A beam of unpolarized light with an intensity of 1000 W/m² impinges on a set of two linear polarizers with their polarization axes at an angle $\theta$ relative to each other.If the light transmitted through this combination has an intensity of 250 W/m²,what is $\theta$ ?

A) 0 ^$\circ$
B) 22.5 ^$\circ$
C) 45 ^$\circ$
D) 67.5 ^$\circ$
E) 90 ^$\circ$
