Choose the figure which is different from the rest.

   (1)     (2)     (3)     (4)     (5)

The pins, equal in number to the number of sides in the main figure are attached to the midpoint of a side of the main figure in case of figures (2), (3), (4) and (5). In fig. (1), these pins are attached to a vertex of the main figure.

In one step, the two elements interchange positions and the smaller element gets enlarged while the larger element gets reduced in size. In the next step, the smaller element is replaced by a new small element and the larger element is replaced by a new large element.

The elements move in the sequences and alternately. Also, in each step, the element that reaches the encircled position, gets replaced by a new element.

In each step, one dot is lost while another dot is replaced by a cross.

In each step, the symbols move in the sequence and the symbol that reaches the encircled position gets replaced by a new one.

In all other figures, the arrow and the V sign lie towards the black end of the main figure.

In all other figures, there are two small line segments towards the pin and three small line segments towards the arrow.

The lines outside the shaded circle are not equally distributed along the circumference in fig. (2).

In all other figures, the lower-right quarter portion is shaded.

Only in fig. (5), the arrowhead along the circumference of the circle indicates motion in an ACW direction.
