A piece of paper is folded and punched as shown below in the question figures. From the given answer figures, indicate how it will appear when opened.


- AA
- BB
- CC
- DD
Solution & Step-by-step Explanation
Let's trace the unfolding process step by step:When the final fold is opened up, the holes punched near the folded margins replicate symmetrically across the fold lines.Since the punches are symmetric along the quadrant creases, opening the paper completely generates a uniform distribution of circular cuts mirrored equally across the horizontal and vertical axes of symmetry.Analyzing the layouts of the options, Figure A perfectly matches the resulting configuration of holes upon unfolding.
