Question 4

AI reconstruction. Which pictured piece fills exactly the white cells inside the complete 7 by 7 square? The square is shown tilted as a diamond. Keep every already colored cell. Match cell sizes, retain the pictured orientation and the relative positions of all disconnected parts, and do not rotate or reflect the piece. Treat the drawn grid as equal cells.
