A particle of mass m is projected from the ground with an initial speed `u_0` at an angle `alpha` with the horizontal. At the highest point of its trajectory, it makes a completely inelastic collision with another identical particle, which was thrown vertically upward from the ground with the same initial speed `u_0.` The angle that the composite system makes with the horizontal immediately after the collision is

A

`(pi)/(4)`

B

`(pi)/(4)+alpha`

C

`(pi)/(4)-alpha`

D

`(pi)/(2)`
