Option B contains two overlapping motifs — one normal and one mirror-flipped — placed so they overlap at the center. The left half of that overlapping pair matches the target motif (X) exactly (arch above chevron). Because one motif is mirrored and they overlap, the target is camouflaged — this is a classic mirror-hiding + overlap trick.

Option D embeds the rotated L-with-circle subtly within a shaded grid, matching (X)’s shape.

Option C hides the curved arrow (X) subtly along a shaded arch inside the rectangle.

Option D hides the zigzag line from figure (X) within its rectangular pattern; the angles and sequence match exactly.

Option C contains the complete 5-point star (rotated slightly) embedded among background shapes. The other options have fragments or star-like noise but not a full 5-point star.
