- AOption A
- BOption B
- COption C
- DOption D
Solution & Step-by-step Explanation
Let's follow the unfolding sequence backward to see where the punch cuts replicate symmetrically across the grid lines:
The sheet is folded twice to form a quadrant sector (
4
1
of a circle).
Two cuts are punched along the outer circumference arc edge.
Unfolding it once vertically creates mirror symmetric images along the fold line line, resulting in 2×2=4 cuts.
Unfolding it fully back to the circular form replicates the pattern into all four quadrants.
Since the cuts were on the outer boundary edge, all final punched shapes will be symmetrically distributed along the outer circumference margin of the fully opened circle, totaling 8 cuts uniformly spaced. This perfectly matches the pattern shown in Option D.
