Identify the figure from the given options that completes the pattern in figure (X).

By observing the grid in figure (X), we can see a clear pattern of symmetry across the four quadrants:
1. Each quadrant contains a diagonal line originating from its outer corner and extending towards the center of the main square.
2. On each diagonal line, there are 3 arrowheads pointing outwards toward the outer corner of that quadrant.
3. Each outer corner contains two concentric arcs.

To complete the bottom-right quadrant:

* The diagonal line must run from the bottom-right corner towards the center.
* The 3 arrowheads on this line must point down and to the right (towards the bottom-right corner).
* There must be two concentric arcs located exactly in the bottom-right corner.

This perfectly matches the configuration shown in Figure (B).
