The balls, having linear momenta `vecp_1=vecpi and vecp_2_2=-vecpi`, undergo a collision in free space. There is no external force acting on the balls. Let `vecp'_1 and vec p'_2` be their final momenta.The following option (s) is (are) NOT ALLOWED for any non-zero value of `p, a_1, a_2, b_1, b_2, c_1 and c_2`.

A

`vecp_1'=a_1 hati+b_1 hatj + c_1 hatk , vecp_2'= a_2hati+b_2hatj`

B

`vecp_1'=c_1 hatk , vecp_2' = c_2hatk`

C

`vecp_1' =a_1hati+b_1hatj + c_1 hatk , vecp_2'= a_2hati+b_2hatj-c_1 hatk`

D

`vecp_1' = a_1hati+b_1hatj , vecp_2'= a_2hati+ b_2hatj`
