त्रिकोण मिळवण्यासाठी कागदाच्या चौरस तुकड्याची तुटक रेषेवरून घडी घातली आणि त्या त्रिकोणाला विविध आकारांनी दाखवल्याप्रमाणे छिद्रे पाडली, छिद्रे पाडल्यावर उलगडलेल्या कागदाप्रमाणे दिसणारी प्रतिमा निवडा.

The correct answer is Option A (Option (1) unfolded pattern).

Key Points:
• Solving paper folding and punching systematically:
• A square paper is folded diagonally to form a right-angled triangle.
• Punches made on this triangular flap are: a circle punched along the hypotenuse/crease, a triangular notch at the corner, and cutouts along the edges.
• Unfolding along the diagonal crease produces a symmetric reflection across the diagonal line.
• Points along the folded crease duplicate into symmetric pairs across the diagonal, forming complete symmetrical shapes (such as diamonds and symmetric circular pairs around the center).
• Tracing the mirror reflections of each punched hole across the diagonal axis produces the exact pattern shown in Option (1).
• Hence, Option (1) is the correct unfolded paper representation.
• Key Takeaway: Unfolding the diagonally folded square mirrors all punched cuts across the central diagonal, yielding pattern (1).
