The next series is most probably going to be option D. 
We can see from the series that, figure 1 has 4 points marked on the circle from which they formed a rectangle.
In the next figure, there are 3 points marked which together when joined forms a triangle.
Then the next circle has 2 points marked on it which makes a straight line.
So, obviously the next figure/circle in the series should have only 1 point marked on it. This won't form anything as you can't join just 1 point with something.
