A large rectangular box moves vertically downward with an acceleration `a`. A toy gun fixed at `A` and aimed towards `C` fires a particle `P`.

A

P will hit C if a = g

B

P will hit the roof BC, if `a gt g`

C

P will hit the wall CD if `a lt g`

D

May be either (A), (B) or (C), depending on the speed of projection of P
