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 analyze the steps of folds and punches:
The paper is folded along diagonal lines or quadrants down to a smaller square/triangle corner section.
A punch/cut pattern is created along the edge or center.
When unfolding the paper step by step, the pattern will mirror perfectly across each fold axis line (producing symmetric layouts across both vertical and horizontal center lines).
Re-aligning these punches reveals that the holes create symmetric arrays distributed in four quadrants around the center, which matches option A.
