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 track the unfolding process of the paper step-by-step:
When the paper is folded twice (quadrants) and a punch or cut is made near the center/edges, unfolding it creates symmetric reflections across both axes (horizontal and vertical).
The punches made on the triangular corner or folded edge will replicate symmetrically in all 4 quadrants, forming a symmetric pattern around the center of the square paper.
Looking at the standard configuration for this question pattern, Option A properly displays the symmetrical positioning of the four identical punched patterns in each corner/quadrant.
