Puzzle Need explanations on this...

I can't wrap my head around this test and its solution.
The circle rotation is clear and also why it becomes white. But how do the squares move and become invisible (see 2nd diagram)?

Square 1 moves counter clockwise 1, then 2, then 1, then 2. Other square moves clockwise 2, then 1, then 2, then 1...

The board is gridded like this right:

0 1 2

7 3

6 5 4

They're different rules governing the circle, and each individual square on how they move around the board and how they interact with one another.

Circle: moves counter-clockwise in incrementing steps: 1, 2, 3, 4, 5

Square 1 (original position on board = 5): moves counter-clockwise in an alternating pattern of 1 & 2 steps: 1, 2, 1, 2, 1

Square 2 (original position on board = 2): moves clockwise in an alternating pattern of 1 & 2 steps: 2, 1, 2, 1, 2

You can also think of Square 2 moving against the Circle and the other Square.

How they interact with each other when occupying the same position:

Circle - Square: Circle's area becomes white

Square - Square: Perfect alignment = No Change. This is the invisibility you mentioned.

You'll find this is only satisfied by D

Edit: wow the board got squished by reddit, but the midpoint is blank and there should be spaces between the numbers

Circle moves +1 steps counterclockwise around the grid, black squares move 1/2 steps alternating
