Answer: B. A square diamond in the centre and 4 circular holes

Answer: (B) A square diamond in the center and 4 circular holes.
Explanation:
• Because the paper was folded into quadrants (4 layers) meeting at the central point, the central triangular notch mirrors outward 4 times, creating a central square diamond shape.
• The single circular hole punched into the layered corner will replicate across all 4 quadrants, resulting in 4 circular holes symmetrically spaced around the paper.
