Complete the figure.

Each 2x2 block on the right is obtained from the 2x2 block on the left by changing the shape while keeping the color (fill). Row 1-2: filled circle becomes filled rect, open rect becomes open circle, filled triangle becomes filled diamond, open diamond becomes open triangle. Applying the same to row 3-4 (open triangle, filled diamond / open rect, filled circle) gives open diamond, filled triangle / open circle, filled rect. This matches option 3.
