To determine which option is not possible without flipping the pieces, we need to evaluate the spatial arrangement of each option using visualization techniques. We'll proceed with a piece-by-piece alignment approach:
Identify the basic pieces: Mentally or physically separate each given option into its fundamental pieces that match the provided set. These may resemble typical puzzle components or geometrical shapes.
Examine each option: For each arrangement option provided:
Refer to the original orientation of the pieces. Attempt to construct each presented option by rotating the pieces, staying within the constraint of not flipping them.
If a piece seemingly fits only after a flip, note that this option cannot be formed under the given rules.
Comparison of pieces: Analyze the specific placement of each piece, checking for alignment and orientation. Identify impossible positions through logic deduction where flipping would be necessary.
Solution conclusion: Through analysis, is identified as the configuration not possible without flipping. This option requires a flipped piece that either doesn't fit the base outline or align with the remaining joining pieces, contradicting the non-flipping rule.
