A tower of x metres height has flag staff at its top. The tower and the flag staff subtend equal angles at a point distant y metres from the foot of the tower. Then, the length of the flag staff in metres is

A

`y(x^(2)-y^(2))/(x^(2) + y^(2))`

B

`x(y^(2)+x^(2))/(y^(2)-x^(2))`

C

`x(x^(2)+y^(2))/(x^(2)-y^(2))`

D

`x(x^(2)-y^(2))/(x^(2) + y^(2))`
