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 steps:
The paper is folded twice diagonally/quadrant-wise, and small circular cuts/punches are made near the center edge.
Unfolding it once duplicates the cuts symmetrically across the fold axis.
Completely opening the sheet spreads the punches uniformly across all four quadrants relative to the center axes.
This symmetric distribution creates a pattern matching Figure A.
