Step 1: Observing the shapes.
Each option contains two arc-like curves. In three of the shapes, the curves follow a consistent rotational pattern and maintain similar spacing and direction.
Step 2: Explanation.
Option C differs because the inner and outer arcs do not follow the same curvature pattern seen in A, B, and D. In C, the alignment and spacing between the curves break the visual consistency, making it structurally different from the rest.
Step 3: Conclusion.
Therefore, the odd one out based on curvature orientation and spacing is Option C.
