From a tower of height H, a particle is thrown vertically upwards with a speed u. The time taken by the particle, to hit the ground, is n times that taken by it to reach the highest point of its path. The relation between H, u and n is

A

`2gH = "nu"^(2)(n-2)`

B

`gH = (n-2)u^(2)`

C

`2gH = n^(2)u^(2)`

D

`gH = (n-2)^(2)u^(2)`
