Find out the alternative figure which contains figure (X) as its part.

     (X)                (1)         (2)         (3)        (4)

In each row, the second figure is obtained by removing the outermost element of the first figure and the third figure is obtained by removing the outermost element of the second figure.

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
