Select a suitable figure from the four alternatives that would complete the figure matrix.

In each row (as well as in each column), the number of rectangles in the second figure is two times the number of rectangles in the first figure and the number of rectangles in the third figure is three times the number of rectangles in the first figure.

There are 3 types of shadings in the triangles, 3 types of legs, 3 positions of circles, each of which is used only once in a single row. The circle is shaded in alternate figures.

In each row, the third figure is a combination of the first and the second figure.

In each row (as well as each column), the third figure is a combination of all the, elements of the first and the second figures

In each row, the triangle follows the circle, the square follows the triangle and the circle follows the square. In case of the third row, the above rule exists for the inner as well as the outer elements.
