the velocity of c is v because the masses of the three  balls  are same , therefore the the velocities are transfered . so the correct option is A

The answer is v (a.)

Solution: When a body collides elastically with an another body, the two intechanges their velocities.

In this case body A moving with velocity v collides with an another body B at rest , as such after the collison the two balls interchange their velocites and B starts moving with velocity v and A comes to rest.

Similar case happens when body B collides with body C. The two interchange their velocites and C began to move with a velocity equal to v and body B comes to rest
