So I know the position of the square. I am stuck with the colors and I do not understand the position of the two smaller rhombuses.
I think the answer is:
B, second image from the top
The square pattern is moved 3 steps around the sides clockwise. Then the white pattern is always in the third row. So the only answer that matches the square pattern and the white pattern is B. I'm still working for the other shape's pattern.
From the answer, I guess the rhombuses' patterns are one of them moves down one step, and one of them is moved around the sides one step counter clockwise.
