Three balls `A,B` and `C` are projected from ground with same speed at same angle with the horizontal.The balls `A,B` and `C` collide with the wall during a flight in air and all three collide perpendicularly and elastically with the wall as shown in figure.If the time taken by the ball `A` and fall back on ground is `4` seconds and that by ball `B` is `2 seconds`Then the time taken by the ball `C` to reach the ground after projection will be
