To determine the correct fold lines when the sheet is unfolded, we start by analyzing the given folded paper. The paper has a green side and a red side, with dotted lines indicating its folds. You must imagine how these folds would appear once the sheet is entirely unfolded.
Here are the logical steps to reach the solution:
By this inspection process, the image insuitably represents these unfolded patterns and reflects symmetrical coherence when comparing visible characteristics.
Conclusively, option 1 is the correct answer, appropriately visualizing the unfolded sheet with accurate fold lines and color allocation.
