Directions: In the following question, a part of the figure is missing. Find from the given options (a, b, c and d) the right figure to fit in the missing part.
The main square is divided into four equal quadrants with a diagonal drawn in each small square from the top-left corner to the bottom-right corner. Concentric circular arcs are parts of a single circle centered at the intersection of the two midlines; each quadrant shows the continuation of these arcs.
Therefore, in the bottom-right quadrant, the diagonal must run from its top-left to bottom-right corner, and the circular arcs must appear as the continuation of the same concentric circle—i.e., concave towards the center and opening to the right/down.
Among the options, only (c) matches both the diagonal orientatio} and thecorrect curvature/placement of the two concentric arcs.
\(\boxed{\text{Option (c)}}\)
