Numbered balls roll down ramps. The order of the balls changes as they fall into holes. When a ball comes to a hole, if there is enough space, the ball falls in, otherwise, the ball rolls past the hole. A pin at the bottom of each hole can be pulled which ejects the balls.
Here is an example:
Ten balls roll down the ramp shown below.
Three holes A, B and C have space for 3, 2 and 1 balls as shown.
The pins are pulled in the order A, B, C but, each time, only after all the balls have stopped rolling.
Question:
Which of the following is the final result?
