Select the figure from among the given options that can replace the question mark (?) in the following series.

From the first to the second box, 'P' moved one step in the anticlockwise direction and rotated horizontally. 'E' moved one step in the clockwise direction and rotated horizontally.

From the second to the third box, 'P' moved one step in the anticlockwise direction and rotated horizontally. 'E' moved one step in the clockwise direction and rotated horizontally.

From the third to the fourth box, 'P' moved one step in the anticlockwise direction and rotated horizontally. 'E' moved one step in the clockwise direction and rotated horizontally.

Similarly, from the fourth to the fifth box, 'P' will move one step in the anticlockwise direction and rotate horizontally. 'E' will move one step in the clockwise direction and rotate horizontally.

By this options (c) and (d) can be eliminated.

Now from one box to another one, in the middle figure, one line is increased to make a shape. By this option (a) can also be eliminated.

Hence the figure given in option (b) will come in place of the question mark.
