What will come in place of?:

All others are Consonants. IInd logic : All others are open figures. So , figure ( 4 ) is required answer .

On the basis of given figures in above question , we can see that
From first figure to second figure two black dots are added in the upper part and two white circles in the lower part. The same procedure is continued in the subsequent figure.
Hence , figure ( 4 ) will come on the place of ? from answer figures .

As per the given figure in above question, it is clear that
In each subsequent figure the shaded part and circle move one step in clockwise direction.
Therefore , figure ( 3 ) will come on the place of ? in question figure .As shown in answer figures .

NA

Except in figure (2), in all other figures there are four line segments with small circle. But all other figures are different to figure ( 2 ) .

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

NA

Half of the figure is missing and the remaining half is in shaded form.
