One side of a rectangular piece of paper is \( 6 \mathrm{~cm} \), the adjacent sides being longer than \( 6 \mathrm{~cm} \). One corner of the paper is folded so that is sets on the opposite longer side. If the length of the crease is \( l \mathrm{~cm} \) and it makes an angle \( \theta \) with the long side as shown, then \( l \) is
(a) \( \frac{3}{\sin \theta \cos ^{2} \theta} \)
(b) \( \frac{6}{\sin ^{2} \theta \cos \theta} \)
(c) \( \frac{3}{\sin \theta \cos \theta} \)
(d) \( \frac{3}{\sin ^{2} \theta} \)
