A disc of mass `m` and radius `R` is kept on a smooth horizontal surface with its plane parallel to the surface. A particle of same mass `m` travelling with speed `v_(0)` collides with the stationery disc and gets embedded into it as shown in the figure. Then

A

Angular momentum of (disc + particle) system can be conserved only about cenre of the disc

B

The speed of centre of mass of the system is `(v_(0))/(2)` after collision

C

The angular speed of the system after collision is `(v_(0))/(2R)` about `C.M.` of the disc + particle system

D

The K.E. of the system is conserved during the collision.
