One ball from the right rolls out with a speed 2 v and the remaining balls will remain at rest
B
Two balls from the right roll out with speed v each and the remaining balls will remain stationary
C
All the six balls in the row will roll out with speed v /6 each and the two colliding balls will come to rest
D
The colliding balls will come to rest and no ball rolls out from right
