A beam of unpolarized light of intensity $\displaystyle I_0$ is passed through a polaroid $\displaystyle A$, then through another polaroid $\displaystyle B$, oriented at $\displaystyle 60$° and finally through another polaroid $\displaystyle C$, oriented at $\displaystyle 45$° relative to $\displaystyle B$ as shown. The intensity of emergent light is:
