Solution & Step-by-step Explanation
Let's trace the unfolding process step by step:
The paper is folded in half, and then into quadrants (one-fourth slice).
Two holes are punched near the circular curved edge of this quadrant slice.
Unfolding it once to a semicircle will mirror these 2 holes across the fold axis, producing 4 holes.
Unfolding completely back into a full circle will mirror all 4 holes to the opposite side, resulting in a symmetrical ring layout of 8 holes evenly spaced along the outer perimeter.
This pattern perfectly matches option figure A.
