Select the figure which satisfies the same conditions of placement of the dots as in Figure-X.

Answer B

As per the given figure in above question, it is clear that
From Problem Figure (2) onwards the outer design moves one sector in clockwise direction.
Thus , figure ( 4 ) will come on the place of ? in question figure .As shown in answer figures .

In each row, the second figure is obtained from the first figure by adding two mutually perpendicular line segments at the centre and the third figure is obtained from the first figure by adding four circles outside the main figure.

Every time the centre figure (circle and the radius) moves 90 degree clockwise.

According to given question figure ,
we can say that the mirror image always be opposite the original image across the given line. It will become opposite in mirror across the given line MN.

The open sides of the outer and middle designs face different directions except in figure (3). But all others are different to figure ( 3 ) .
