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

In each row, the second figure forms the innermost and the outermost elements of the third figure and the first figure forms the middle element of the third figure.

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.

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 third figure is a combination of the first and the second 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.

The third figure in each row comprises of parts which are not common to the first two figures.

In each row, there are three types of outer elements (circle, triangle and square), three types of inner elements (circle, triangle and square) and three types of shadings in the inner elements (black, white and lines).

In each row, there are three types of arrows - an arrow with a single head and without any base, an arrow with double head having a circle at its base, an arrow with triple head having a rectangle at its base. Also, in each row, the arrows point in three directions - upwards, downwards and towards the right.

In each row, the number of elements in the third figure is equal to the difference in the number of elements in the first and second figures. Also, the third figure has the same types of elements (if any) as the elements in the first figure.

In each row, the second figure is obtained by rotating the first figure through 90 ^o CW or 90 ^o ACW and adding a circle to it. Also, the third figure is obtained by adding two circles to the first figure (without rotating the figure).
