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 `agt g`

C

`P` will hit the `CD` if `alt g`

D

May be either (a), (b) or (c) depending on the speed of projection of `P`.
