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.

Following the reverse process of unfolding the paper step by step:
Unfolding the final corner fold will mirror the punches along the diagonal/crease lines.

Unfolding the complete page back to its original layout duplicates these punch patterns symmetrically across both axes.

This symmetric distribution of holes perfectly aligns with the position shown in figure A.
