>>111249161st one:
common from first 2 in each row get flipped vertically
so A
2nd:
idk
but my intuition tells me it's D
3rd:
diagonal pattern to the left from the top row, i.e. down and left from each on the top row, there is one change so going by that it's
E
4th one
position for white balls in last one is the positions unoccupied in first two of each row
black occupies 2 types of positions in each row; easy to see
so it's F
