>>11628019 the bottom left/bottom right square with one diagonal crossed (like this \ or this /) indicates the orientation of the black shape.
To exemplify, when the one crossed square is at the bottom-left the black shape looks like an H (though it's more complicated than just that), when the crossed square is at the bottom-right, the black shape looks like an uppercase i.
It also indicates the orientation of the squares with two crosses.
Now the black shape has a z-index lower than the one-cross square or the two-cross squares. Therefore, the other squares appear on top of the black squares.
The squares with two crosses go increasing one by one.
The black squares go decreasing one by one (The first and second cases hide this, but by the third case and fourth case you can already see one square missing from the original design, so it makes sense that it goes decreasing.
Now the A answer would imply that the square with one diagonal is on the top-right. The reason why there are two rotations is because it completes the whole set of rotations: 90 degrees, 270 degrees, 0 degrees, and of course this one would be 180 degrees.
