One side of a rectangular piece of paper is 6 cm, the adjacent sides being longer than 6 cms. One corner of the paper is folded so that it sets on the opposite longer side. If the length of the crease is `l` cms and it makes an angle `theta` with the long side as shown, then `l` is

A

`(3)/(sin theta cos^(2)theta)`

B

`(6)/(sin^(2)thetacos theta)`

C

`(3)/(sin theta cos theta)`

D
