Correct Answer: C
Explanation:
The shaded and light parts of each circle inverse (interchange) to give us the 2nd diagram. Then both circles on the right side simply change positions with left side circles without inversion of shaded parts. Now again the shaded and light parts of each circle inverse their positions. Again, circles on right should exchange positions with circles with left without inversion. So, answer figure (b) is correct. So, the answer is option c.
