Hint 1 of 2
The big design is one repeating pattern; the white window is just a square-shaped hole punched out of it.

Hint 2 of 2
Look at the lines touching all four edges of the hole and ask which piece lets every one of them continue without a break.
Show solution
Approach: match the missing tile to the lines around the hole
- The hole sits inside a repeating pattern of overlapping squares and diamonds, so the right piece is the one that keeps every line going straight across the gap.
- Trace the lines that arrive at the top, bottom, left and right edges of the white square; the correct piece must connect to all of them at once.
- Only choice C lines up on all four sides so the pattern stays seamless with no broken lines, so the answer is (C).
