Find the missing figure from the given options.

The correct answer is Option (4) → 

Each figure is the previous one flipped top to bottom (its mirror image in a horizontal line), with one more circle blackened and one plus sign removed. Flipping (B) brings its two black circles to the top-left end of the line and its two white circles to the lower end; the first of these turns black, leaving one white circle in the bottom-right corner. A quarter turn would not do: it would stand the pair ‘+ +’ of (A) on end, but in (B) the pair is still side by side.
