Step 1: Observe the cuts.
The folded paper has triangular and square cut-outs along its creases. When unfolded, these cuts replicate symmetrically across all folds.
Step 2: Predict unfolding.
- Cuts along one folded flap will appear 4 times after unfolding.
- Hence, the final shape must have repeated diamond/square holes across the entire sheet.
Step 3: Compare options.
- (A): Shows multiple symmetric diamond-shaped holes spread evenly – matches predicted result.
- (B), (C), (D): Do not match the symmetry or number of holes formed by the shown cuts.
Step 4: Conclude.
The unfolded figure must be (A).
Final Answer:
\[
\boxed{\text{A}}
\]
