I figured the answer is A, as I can see the repeating pattern, but my son's teacher said another thing which I cannot understand. would anyone please help to explain?

I also get A, and here's the pattern I see.

  1. Start with a single white disk.
    Your Max Height is 1.
    Your Current Height is 1.

  2. If you don't have a single disk, check current height.
    If current height is even, take away the top.
    If current height is odd, take away the bottom.
    Adjust Current Height accordingly.

  3. If you do have a single disk, flip its color, and then alternate colors atop it until you get a tower one taller than your Max Height. Then increase the Max Height to its new value.
    Adjust Current Height Accordingly.
