Three polaroid sheets are kept parallel to each other such that first and last are crossed. Unpolarised light of intensity \(32 \mathrm{Wm}^{-2}\) falls normally on the first sheet and passes through all the polaroid sheets. If the intensity of the emerging light from the third sheet is \(3 \mathrm{Wm}^{-2}\), then the angle between the axes of the first two polaroid sheets is
- A \(60^{\circ}\)
- B \(45^{\circ}\)
- C \(30^{\circ}\)
