How would the pattern given on the square transparent sheet marked ‘X’ look when the sheet is folded along the dotted line?
(Note: The transparent sheet contains a symmetrical geometric drawing on both left and right halves, split by a central vertical dotted line.)

When a transparent sheet is folded along a vertical dotted line, the pattern on one side flips horizontally (like a mirror image) and superimposes perfectly on top of the design on the other side.
By analyzing the overlapping lines from the flip, the combined shapes create a brand new symmetric design, which is correctly and precisely represented in Option A.
