The problem figure sequence shows a specific pattern of transformations. Let's analyze the sequence step by step to determine the pattern and identify the correct figure to replace the question mark:
We need to determine the transformation for the fourth figure based on the pattern:
The first two figures represent a symmetry of curves, followed by a zig-zag pattern. The zig-zag pattern does not change orientation, indicating that the sequence is repeating this pattern. Thus, the zig-zag orientation remains the same from the third to the fourth figure.
Therefore, option A, which matches the orientation of the zig-zag line in the third figure, is the correct choice.
