    In figure X the square sheet of paper has been folded along the horizontal line of the symmetry on the top side.

    In figure Y, the sheet is folded further similarly on the other side. Again in figure Z, two circles are punched one on the folded part and another on the unfolded end.

    One circle punched on the folded part will be reflected three times and the circle punched on unfolded will be reflected only once. Thus, when the paper is unfolded four circles are seen symmetrically on one corner and one circle is seen in the centre.

    Hence option C is correct.
