A ball is thrown at an angle `theta` up to the top of a cliff of height L, from a point at a distance. L from the base, as shown in figure. Assuming that one of the following quantities is the initial speed required to make the ball hit right at the edge of the cliff, which one is it :-

A

`sqrt((gL)/(2(tan theta-1)))`

B

`1/(cos theta) sqrt((gL)/(2(tan theta-1)))`

C

`1/(cos theta) sqrt((gL)/(2(tan theta+1)))`

D

`sqrt((gL)/(2(tan theta+1)))`
