A ball collides elastically with a massive wall moving towards it with a velocity of `v` as shown. The collision occurs at a height of `h` above ground level and the velocity of the ball just before collision is `2v` in horizontal direction. The distance between the foot of the wall and the point on the ground where the ball lands, at the instant the ball lands, will be `:`

A

`vsqrt((2h)/(g))`

B

`2vsqrt((2h)/(g))`

C

`4vsqrt((2h)/(g))`

D

`3vsqrt((2h)/(g))`
