In the figure \( \mathrm{ABC} \) is the cross section of a right angled prism and \( \mathrm{BCDE} \) is the cross section of a glass slab. The value of \( \theta \) so that light incident normally on the face \( A B \) does not cross the face \( \mathrm{BC} \) is (given
P \( \left.\sin ^{-1}(3 / 5)=37^{\circ}\right) \)
(A) \( \theta \leq 37^{\circ} \)
(B) \( \theta37^{\circ} \)
(C) \( \theta \leq 53^{\circ} \)
(D) \( \theta53^{\circ} \)
